Take a look there +first. + +As this sample provides a web app there is a manual step where the WAR file +that contains the sample is copied to your web app container. If you just want +to give this sample a go deploy the WAR file (target/sample-helloworld-jsonrpc-webapp.war) +to you web application server. + +Once the web app is deployed use your browser to visit the following URL; + +http://localhost:8080/sample-helloworld-jsonrpc-webapp + +The port and hostname will of course vary depending on your local installation. + +Sample Overview +--------------- +The sample provides a single service with an operation that reflects +a greeting back to the caller. The service is exposed using the JSONRPC +binding. The web app provided shows how the SCA-provided JSON client can be +used to invoke the SCA service. + +helloworld-jsonrpc-webapp/ + src/ + main/ + java/ + helloworldjsonrpc/ + HelloWorldService.java - service interface + HelloWorldServiceImpl.java - service implementation + resources/ + jsonrpc.composite - the SCA assembly for this sample + webapp + META-INF/ + sca-contribution.xml - specifies the composite to be deployed + WEB-INF/ + web.xml - defines the listener that starts up the + Tuscany SCA runtime + HelloWorldJSONRPC.html - the web application that calls the + SCA service via JSONRPC + style.css - style sheet + + helloworld-jsonrpc-webapp.png - a pictorial representation of the + sample .composite file + build.xml - the Ant build file that unpacks the + dojo installation + pom.xml - the Maven build file + +Building And Running The Sample Using Ant +----------------------------------------- +With the binary distribution the sample can be built using Ant as +follows + +cd helloworld-jsonrpc-webapp +ant package + +This should result in a war file (sample-helloworld-jsonrpc-webapp.war) in the target +directory. Copy this war file to your web app deployment directory in your +web app container. + +The process for getting the web app running will depend on which web app container +you are using. For example, if you are using Tomcat then it is simply a matter +of copying the WAR file to the webapps directory. + +Once the web app is deployed use your browser to visit the following URL; + +http://localhost:8080/sample-helloworld-jsonrpc-webapp + +The port and hostname will of course vary depending on your local installation. + +You should see a web page that allows you to send messages, via JSONRPC, to the +application running in the Tuscany SCA Runtime + +Building And Running The Sample Using Maven +------------------------------------------- +With either the binary or source distributions the sample can be built and run +using Maven as follows. + +cd helloworld-jsonrpc-webapp +mvn + +Again this should result in a war file (sample-helloworld-jsonrpc-webapp.war) in the target +directory.
