The service implementation +uses a country repository to fetch the necessary data. + +By adding <tuscany:binding.comet/> to a service definition, the Tuscany runtime +will handle the communication between the browser client and the service +implementation using Comet techniques. This enables bidirectional communication +over HTTP, therefore enabling server push. For more information, check +http://en.wikipedia.org/wiki/Comet_(programming). + +The comet binding is using the Atmosphere Framework under the hood to acomodate +as many deployment envorinments as possible. Basically, it checks if the +application server supports Servlet 3.0 falling back to a number of native +comet solutions provided by vendors (Jetty, Tomcat, WebLogic, GlassFish and +others). If none is available, Atmosphere will fallback to blocking IO. + +Invoking comet services can be done using Tuscany's javascript API which simulates +SCA in the browser. It uses the Atmosphere jQuery plugin under the hood. In order +to use it, the following script has to be included in the client page: + <script type="text/javascript" + src="tuscany-comet-js/org.apache.tuscany.sca.CometComponentContext.js"> + </script> + +The javascript toolkit permits choosing between two comet techniques: HTTP streaming +and long polling. More detailed information about them can be found on the previously +mentioned wikipedia page. + +First, a connect operation has to be issued in order to initiate communication +with the server side using the technique of your choice. This is done using the +connection method as follows: + SCA.TuscanyComet.connect('streaming'); // for HTTP streaming + SCA.TuscanyComet.connect('long-polling'); // for long polling + SCA.TuscanyComet.connect(); // starts with HTTP streaming and falls back to long polling if necessary + +The Tuscany Comet toolkit will inject proxies for all services defined in the composite +that are using binding.comet. All invocation and connection management is handled +under the hood so in order to invoke a comet service, the following should be called: + SCA.CometComponentContext.<service name>.<operation name>(<parameters>, callback); + +The callback parameter is the function that will handle responses received for a +certain service operation. It has a single argument which is the response: + function callback(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so the +parameters should have the same structure as the data types defined in the method +definition. Also, the response will have the same data type as the return type of +the service method. Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single HTTP +connection to handle communication between a browser client and all services +defined using binding.comet in the same composite. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. This is done in order to avoid +the 2 HTTP connection limit imposed by browsers. For more info, check +http://www.openajax.org/runtime/wiki/The_Two_HTTP_Connection_Limit_Issue. + +In order to run the sample, you can execute "mvn clean install t7:run" which will +start a Tomcat 7 instance automatically or use "mvn package" and deploy the resulting +war to the application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-comet-autocomplete-webapp/ + +You can see how suggestions are being received in real time when characters are +entered in the text field. You can see the persistent HTTP streaming connection +or long polling subsequent connections using the developer tools provided by +your browser. + +The comet binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).

It +also demonstrates how to push multiple responses for a single request using +SCA callbacks via comet techniques. + +This project contains a service (ChatService) that handles chat operations like +register and postMessage. Once a client is registered it will receive messages +that are sent to the chat room. + +By adding <tuscany:binding.comet/> to a service definition, the Tuscany runtime +will handle the communication between the browser client and the service +implementation using Comet techniques. This enables bidirectional communication +over HTTP, therefore enabling server push. For more information, check +http://en.wikipedia.org/wiki/Comet_(programming). + +The comet binding is using the Atmosphere Framework under the hood to acomodate +as many deployment envorinments as possible. Basically, it checks if the +application server supports Servlet 3.0 falling back to a number of native +comet solutions provided by vendors (Jetty, Tomcat, WebLogic, GlassFish and +others). If none is available, Atmosphere will fallback to blocking IO. + +In order to enable callbacks to push multiple responses, you need to declare the +CometCallback in the service definition as follows: + <interface.java interface="org.apache.tuscany.sca.sample.comet.ChatService" + callbackInterface="org.apache.tuscany.sca.binding.comet.runtime.callback.CometCallback" /> + <tuscany:binding.comet /> + <callback> + <tuscany:binding.comet /> + </callback> + +The callback object has methods that facilitate sending messages back to the +calling client. It can be injected in the service implementation using the @Callback +annotation. However, the service implementation for this sample has the COMPOSITE +scope so the callback reference has to be obtained from the ComponentContext. + +One requirement that service methods have to meet to enable multiple response +support is that they have to be annotated with @OneWay to enable non-blocking +support. Without it, methods are treated synchronously sending a single response +which is the object returned by the method call. + +Invoking comet services can be done using Tuscany's javascript API which simulates +SCA in the browser. It uses the Atmosphere jQuery plugin under the hood. In order +to use it, the following script has to be included in the client page: + <script type="text/javascript" + src="tuscany-comet-js/org.apache.tuscany.sca.CometComponentContext.js"> + </script> + +The javascript toolkit permits choosing between two comet techniques: HTTP streaming +and long polling. More detailed information about them can be found on the previously +mentioned wikipedia page. + +First, a connect operation has to be issued in order to initiate communication +with the server side using the technique of your choice. This is done using the +connection method as follows: + SCA.TuscanyComet.connect('streaming'); // for HTTP streaming + SCA.TuscanyComet.connect('long-polling'); // for long polling + SCA.TuscanyComet.connect(); // starts with HTTP streaming and falls back to long polling if necessary + +The Tuscany Comet toolkit will inject proxies for all services defined in the composite +that are using binding.comet. All invocation and connection management is handled +under the hood so in order to invoke a comet service, the following should be called: + SCA.CometComponentContext.<service name>.<operation name>(<parameters>, callback); + +The callback parameter is the function that will handle responses received for a +certain service operation. It has a single argument which is the response: + function callback(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so parameters +will be mapped to the data types defined in the method definition. Also, the response +will have the same data type as the server side object used to wrap the response. +Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single HTTP +connection to handle communication between a browser client and all services +defined using binding.comet in the same composite. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. This is done in order to avoid +the 2 HTTP connection limit imposed by browsers. For more info, check +http://www.openajax.org/runtime/wiki/The_Two_HTTP_Connection_Limit_Issue. + +In order to run the sample, you can execute "mvn clean install t7:run" which will +start a Tomcat 7 instance automatically or use "mvn package" and deploy the resulting +war to the application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-comet-chat-webapp/ + +You can now chat using multiple tabs or browsers. You can see the persistent HTTP +streaming connection or long polling subsequent connections using the developer tools +provided by your browser. + +The comet binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).

It +also demonstrates how to push multiple responses for a single request using +SCA callbacks via comet techniques. + +This project contains a component that registers browser clients' interest in a +certain event type. When an event of that type comes in, it notifies all registered +clients. The event processor exposes a service via the websocket binding which +enables server push to clients. Note that Tuscany 2.x doesn't have any conversational +support so this has to be handled at application level by passing ids back and forth +between the client and the server. + +By adding <tuscany:binding.comet/> to a service definition, the Tuscany runtime +will handle the communication between the browser client and the service +implementation using Comet techniques. This enables bidirectional communication +over HTTP, therefore enabling server push. For more information, check +http://en.wikipedia.org/wiki/Comet_(programming). + +The comet binding is using the Atmosphere Framework under the hood to acomodate +as many deployment envorinments as possible. Basically, it checks if the +application server supports Servlet 3.0 falling back to a number of native +comet solutions provided by vendors (Jetty, Tomcat, WebLogic, GlassFish and +others). If none is available, Atmosphere will fallback to blocking IO. + +In order to enable callbacks to push multiple responses, you need to declare the +CometCallback in the service definition as follows: + <interface.java interface="org.apache.tuscany.sca.sample.comet.ChatService" + callbackInterface="org.apache.tuscany.sca.binding.comet.runtime.callback.CometCallback" /> + <tuscany:binding.comet /> + <callback> + <tuscany:binding.comet /> + </callback> + +The callback object has methods that facilitate sending messages back to the +calling client. It can be injected in the service implementation using the @Callback +annotation. + +One requirement that service methods have to meet to enable multiple response +support is that they have to be annotated with @OneWay to enable non-blocking +support. Without it, methods are treated synchronously sending a single response +which is the object returned by the method call. + +Invoking comet services can be done using Tuscany's javascript API which simulates +SCA in the browser. It uses the Atmosphere jQuery plugin under the hood. In order +to use it, the following script has to be included in the client page: + <script type="text/javascript" + src="tuscany-comet-js/org.apache.tuscany.sca.CometComponentContext.js"> + </script> + +The javascript toolkit permits choosing between two comet techniques: HTTP streaming +and long polling. More detailed information about them can be found on the previously +mentioned wikipedia page. + +First, a connect operation has to be issued in order to initiate communication +with the server side using the technique of your choice. This is done using the +connection method as follows: + SCA.TuscanyComet.connect('streaming'); // for HTTP streaming + SCA.TuscanyComet.connect('long-polling'); // for long polling + SCA.TuscanyComet.connect(); // starts with HTTP streaming and falls back to long polling if necessary + +The Tuscany Comet toolkit will inject proxies for all services defined in the composite +that are using binding.comet. All invocation and connection management is handled +under the hood so in order to invoke a comet service, the following should be called: + SCA.CometComponentContext.<service name>.<operation name>(<parameters>, callback); + +The callback parameter is the function that will handle responses received for a +certain service operation. It has a single argument which is the response: + function callback(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so parameters +will be mapped to the data types defined in the method definition. Also, the response +will have the same data type as the server side object used to wrap the response. +Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single HTTP +connection to handle communication between a browser client and all services +defined using binding.comet in the same composite. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. This is done in order to avoid +the 2 HTTP connection limit imposed by browsers. For more info, check +http://www.openajax.org/runtime/wiki/The_Two_HTTP_Connection_Limit_Issue. + +In order to run the sample, you can execute "mvn clean install t7:run" which will +start a Tomcat 7 instance automatically or use "mvn package" and deploy the resulting +war to the application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-comet-chat-webapp/ + +You can now register or unregister for any of a number of events. When an event is fired +on the server side, the browser client will receive a notification which will be displayed +in the page. You can see the persistent HTTP streaming connection or long polling subsequent +connections using the developer tools provided by your browser. + +The comet binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).

It +also demonstrates how to push multiple responses for a single request using +SCA callbacks via comet techniques. + +This project contains multiple services that once called will push notifications +to the client regarding certain weather parameters according to the location of +the user. Of course, the service implementation is a mock that generates random +numbers at a fixed interval of time as weather parameters. + +By adding <tuscany:binding.comet/> to a service definition, the Tuscany runtime +will handle the communication between the browser client and the service +implementation using Comet techniques. This enables bidirectional communication +over HTTP, therefore enabling server push. For more information, check +http://en.wikipedia.org/wiki/Comet_(programming). + +The comet binding is using the Atmosphere Framework under the hood to acomodate +as many deployment envorinments as possible. Basically, it checks if the +application server supports Servlet 3.0 falling back to a number of native +comet solutions provided by vendors (Jetty, Tomcat, WebLogic, GlassFish and +others). If none is available, Atmosphere will fallback to blocking IO. + +In order to enable callbacks to push multiple responses, you need to declare the +CometCallback in the service definition as follows: + <interface.java interface="org.apache.tuscany.sca.sample.comet.ChatService" + callbackInterface="org.apache.tuscany.sca.binding.comet.runtime.callback.CometCallback" /> + <tuscany:binding.comet /> + <callback> + <tuscany:binding.comet /> + </callback> + +The callback object has methods that facilitate sending messages back to the +calling client. It can be injected in the service implementation using the @Callback +annotation. + +One requirement that service methods have to meet to enable multiple response +support is that they have to be annotated with @OneWay to enable non-blocking +support. Without it, methods are treated synchronously sending a single response +which is the object returned by the method call. + +Invoking comet services can be done using Tuscany's javascript API which simulates +SCA in the browser. It uses the Atmosphere jQuery plugin under the hood. In order +to use it, the following script has to be included in the client page: + <script type="text/javascript" + src="tuscany-comet-js/org.apache.tuscany.sca.CometComponentContext.js"> + </script> + +The javascript toolkit permits choosing between two comet techniques: HTTP streaming +and long polling. More detailed information about them can be found on the previously +mentioned wikipedia page. + +First, a connect operation has to be issued in order to initiate communication +with the server side using the technique of your choice. This is done using the +connection method as follows: + SCA.TuscanyComet.connect('streaming'); // for HTTP streaming + SCA.TuscanyComet.connect('long-polling'); // for long polling + SCA.TuscanyComet.connect(); // starts with HTTP streaming and falls back to long polling if necessary + +The Tuscany Comet toolkit will inject proxies for all services defined in the composite +that are using binding.comet. All invocation and connection management is handled +under the hood so in order to invoke a comet service, the following should be called: + SCA.CometComponentContext.<service name>.<operation name>(<parameters>, callback); + +The callback parameter is the function that will handle responses received for a +certain service operation. It has a single argument which is the response: + function callback(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so parameters +will be mapped to the data types defined in the method definition. Also, the response +will have the same data type as the server side object used to wrap the response. +Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single HTTP +connection to handle communication between a browser client and all services +defined using binding.comet in the same composite. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. This is done in order to avoid +the 2 HTTP connection limit imposed by browsers. For more info, check +http://www.openajax.org/runtime/wiki/The_Two_HTTP_Connection_Limit_Issue. + +In order to run the sample, you can execute "mvn clean install t7:run" which will +start a Tomcat 7 instance automatically or use "mvn package" and deploy the resulting +war to the application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-comet-weather-webapp/ + +You can now set a location and register for various weather parameters. Notifications +will be pushed to the browser when weather parameters change. You can see the persistent +HTTP streaming connection or long polling subsequent connections using the developer +tools provided by your browser. + +The comet binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).

The service implementation +uses a country repository to fetch the necessary data. + +By adding <tuscany:binding.websocket port="8090"/> to a service definition, the +Tuscany runtime will start a websocket server listening for requests coming +in for the exposed service at the specified port. If no port is specified, the +runtime will use port 9000 as a default. + +The websocket binding uses embedded Jetty instances as websocket servers. At the +moment, Jetty 8.0.0-M3 is used which has support for the 00, 01, 06 and 07 +versions of the websocket protocol drafts. + +IN ORDER TO RUN THIS SAMPLE SUCCESSFULLY PLEASE CHECK IF YOUR BROWSER SUPPORTS +THE ABOVE WEBSOCKET PROTOCOL VERSIONS AND THAT THE WEBSOCKET SUPPORT IS ENABLED. + +The websocket binding also features a javascript API to simulate SCA in the +browser. In order to use it, the following script has to be included in the +client page: + <script type="text/javascript" + src="org.apache.tuscany.sca.WebsocketComponentContext.js"> + </script> + +This will inject proxies for all services defined in the composite that are +using binding.websocket. All invocation and connection management is handled +under the hood so in order to invoke a websocket service, the following should +be called: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>(<parameters>); + +Given the asynchornous nature of websockets, a function should be defined in +order to handle responses received for a certain service operation. This should +be done as follows: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>.responseHandler = function(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so the +parameters should have the same structure as the data types defined in the method +definition. Also, the response will have the same data type as the return type of +the service method. Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single websocket +connection to handle communication between a browser client and all services +defined using binding.websocket on the same port. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. + +In order to run the sample, you can execute "mvn jetty:run" which will start a Jetty +instance automatically or use "mvn package" and deploy the resulting war to the +application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-websocket-autocomplete-webapp/ + +You can see how suggestions are being received in real time when characters are +entered in the text field. You can see the persistent websocket connection using +the developer tools provided by your browser. + +The websocket binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).

It also demonstrates +how to push multiple responses from the server to the client for a single request +using SCA callbacks. + +This project contains a service (ChatService) that handles chat operations like +register and postMessage. Once a client is registered it will receive messages +that are sent to the chat room. + +By adding <tuscany:binding.websocket port="8090"/> to a service definition, the +Tuscany runtime will start a websocket server listening for requests coming +in for the exposed service at the specified port. If no port is specified, the +runtime will use port 9000 as a default. + +The websocket binding uses embedded Jetty instances as websocket servers. At the +moment, Jetty 8.0.0-M3 is used which has support for the 00, 01, 06 and 07 +versions of the websocket protocol drafts. + +IN ORDER TO RUN THIS SAMPLE SUCCESSFULLY PLEASE CHECK IF YOUR BROWSER SUPPORTS +THE ABOVE WEBSOCKET PROTOCOL VERSIONS AND THAT THE WEBSOCKET SUPPORT IS ENABLED. + +In order to enable callbacks to push multiple responses, you need to declare the +WebsocketBindingCallback in the service definition as follows: + + <interface.java interface="sample.ChatService" + callbackInterface="org.apache.tuscany.sca.binding.websocket.runtime.WebsocketBindingCallback" /> + <tuscany:binding.websocket /> + <callback> + <tuscany:binding.websocket /> + </callback> + +The callback object has methods that facilitate sending messages back to the +calling client. It can be injected in the service implementation using the @Callback +annotation. However, the service implementation for this sample has the COMPOSITE +scope so the callback reference has to be obtained from the ComponentContext. + +One requirement that service methods have to meet to enable multiple response +support is that they have to be annotated with @OneWay to enable non-blocking +support. Without it, methods are treated synchronously sending a single response +which is the object returned by the method call. + +The websocket binding also features a javascript API to simulate SCA in the +browser. In order to use it, the following script has to be included in the +client page: + <script type="text/javascript" + src="org.apache.tuscany.sca.WebsocketComponentContext.js"> + </script> + +This will inject proxies for all services defined in the composite that are +using binding.websocket. All invocation and connection management is handled +under the hood so in order to invoke a websocket service, the following should +be called: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>(<parameters>); + +Given the asynchornous nature of websockets, a function should be defined in +order to handle responses received for a certain service operation. This should +be done as follows: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>.responseHandler = function(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so parameters +will be mapped to the data types defined in the method definition. Also, the response +will have the same data type as the server side object used to wrap the response. +Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single persistent +websocket connection to handle communication between a browser client and all services +defined using binding.websocket on the same port. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. + +In order to run the sample, you can execute "mvn jetty:run" which will start a Jetty +instance automatically or use "mvn package" and deploy the resulting war to the +application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-websocket-chat-webapp/ + +You can now chat using multiple tabs or browsers. You can see the persistent websocket +connection using the developer tools provided by your browser. + +The websocket binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).

It also demonstrates +how to push multiple responses from the server to the client for a single request +using SCA callbacks. + +This project contains a component that registers browser clients' interest in a +certain event type. When an event of that type comes in, it notifies all registered +clients. The event processor exposes a service via the websocket binding which +enables server push to clients. Note that Tuscany 2.x doesn't have any conversational +support so this has to be handled at application level by passing ids back and forth +between the client and the server. + +By adding <tuscany:binding.websocket port="8090"/> to a service definition, the +Tuscany runtime will start a websocket server listening for requests coming +in for the exposed service at the specified port. If no port is specified, the +runtime will use port 9000 as a default. + +The websocket binding uses embedded Jetty instances as websocket servers. At the +moment, Jetty 8.0.0-M3 is used which has support for the 00, 01, 06 and 07 +versions of the websocket protocol drafts. + +IN ORDER TO RUN THIS SAMPLE SUCCESSFULLY PLEASE CHECK IF YOUR BROWSER SUPPORTS +THE ABOVE WEBSOCKET PROTOCOL VERSIONS AND THAT THE WEBSOCKET SUPPORT IS ENABLED. + +In order to enable callbacks to push multiple responses, you need to declare the +WebsocketBindingCallback in the service definition as follows: + + <interface.java interface="sample.ChatService" + callbackInterface="org.apache.tuscany.sca.binding.websocket.runtime.WebsocketBindingCallback" /> + <tuscany:binding.websocket /> + <callback> + <tuscany:binding.websocket /> + </callback> + +The callback object has methods that facilitate sending messages back to the +calling client. It can be injected in the service implementation using the @Callback +annotation. However, the service implementation for this sample has the COMPOSITE +scope so the callback reference has to be obtained from the ComponentContext. + +One requirement that service methods have to meet to enable multiple response +support is that they have to be annotated with @OneWay to enable non-blocking +support. Without it, methods are treated synchronously sending a single response +which is the object returned by the method call. + +The websocket binding also features a javascript API to simulate SCA in the +browser. In order to use it, the following script has to be included in the +client page: + <script type="text/javascript" + src="org.apache.tuscany.sca.WebsocketComponentContext.js"> + </script> + +This will inject proxies for all services defined in the composite that are +using binding.websocket. All invocation and connection management is handled +under the hood so in order to invoke a websocket service, the following should +be called: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>(<parameters>); + +Given the asynchornous nature of websockets, a function should be defined in +order to handle responses received for a certain service operation. This should +be done as follows: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>.responseHandler = function(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so parameters +will be mapped to the data types defined in the method definition. Also, the response +will have the same data type as the server side object used to wrap the response. +Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single persistent +websocket connection to handle communication between a browser client and all services +defined using binding.websocket on the same port. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. + +In order to run the sample, you can execute "mvn jetty:run" which will start a Jetty +instance automatically or use "mvn package" and deploy the resulting war to the +application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-websocket-chat-webapp/ + +You can now register or unregister for any of a number of events. When an event is fired +on the server side, the browser client will receive a notification which will be displayed +in the page. You can see the persistent websocket connection using the developer tools +provided by your browser. + +The websocket binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).

It also demonstrates +how to push multiple responses for a single request using SCA callbacks. + +This project contains multiple services that once called will push notifications +to the client regarding certain weather parameters according to the location of +the user. Of course, the service implementation is a mock that generates random +numbers at a fixed interval of time as weather parameters. + +By adding <tuscany:binding.websocket port="8090"/> to a service definition, the +Tuscany runtime will start a websocket server listening for requests coming +in for the exposed service at the specified port. If no port is specified, the +runtime will use port 9000 as a default. + +The websocket binding uses embedded Jetty instances as websocket servers. At the +moment, Jetty 8.0.0-M3 is used which has support for the 00, 01, 06 and 07 +versions of the websocket protocol drafts. + +IN ORDER TO RUN THIS SAMPLE SUCCESSFULLY PLEASE CHECK IF YOUR BROWSER SUPPORTS +THE ABOVE WEBSOCKET PROTOCOL VERSIONS AND THAT THE WEBSOCKET SUPPORT IS ENABLED. + +In order to enable callbacks to push multiple responses, you need to declare the +WebsocketBindingCallback in the service definition as follows: + + <interface.java interface="sample.ChatService" + callbackInterface="org.apache.tuscany.sca.binding.websocket.runtime.WebsocketBindingCallback" /> + <tuscany:binding.websocket /> + <callback> + <tuscany:binding.websocket /> + </callback> + +The callback object has methods that facilitate sending messages back to the +calling client. It can be injected in the service implementation using the @Callback +annotation. + +One requirement that service methods have to meet to enable multiple response +support is that they have to be annotated with @OneWay to enable non-blocking +support. Without it, methods are treated synchronously sending a single response +which is the object returned by the method call. + +The websocket binding also features a javascript API to simulate SCA in the +browser. In order to use it, the following script has to be included in the +client page: + <script type="text/javascript" + src="org.apache.tuscany.sca.WebsocketComponentContext.js"> + </script> + +This will inject proxies for all services defined in the composite that are +using binding.websocket. All invocation and connection management is handled +under the hood so in order to invoke a websocket service, the following should +be called: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>(<parameters>); + +Given the asynchornous nature of websockets, a function should be defined in +order to handle responses received for a certain service operation. This should +be done as follows: + Tuscany.WebsocketComponentContext.<component name>.<service name>.<operation name>.responseHandler = function(response) { + // handle response + }; + +Note that the data exchange is automatically handled by the binding, so parameters +will be mapped to the data types defined in the method definition. Also, the response +will have the same data type as the server side object used to wrap the response. +Objects are passed over the wire in JSON format. + +Another detail worth mentioning is that the binding will use a single persistent +websocket connection to handle communication between a browser client and all services +defined using binding.websocket on the same port. Requests and responses will get +multiplexed via the same channel and get routed to the appropriate service +implementation, respectively javascript function. + +In order to run the sample, you can execute "mvn jetty:run" which will start a Jetty +instance automatically or use "mvn package" and deploy the resulting war to the +application server of your choice. + +Next, point your browser at + http://localhost:8080/sample-binding-websocket-weather-webapp/ + +You can now set a location and register for various weather parameters. Notifications +will be pushed to the browser when weather parameters change. You can see the persistent +websocket connection handling all the communication using the developer tools provided +by your browser. + +The websocket binding is an experimental binding so community feedback is much +appreciated. Feel free to send comments or suggestions on the Apache Tuscany +dev mailing list (dev@tuscany.apache.org).
