It is very similar to the simple-callback sample. +The only differences are that simplecallback.composite has been updated +to use the Web Service binding, and there is a simplecallback.wsdl file. + +The README in the samples directory (the directory above this) provides +general instructions about building and running samples. Take a look there +first. + +If you just want to run it to see what happens open a command prompt, navigate +to this sample directory and do: + +ant run + +OR if you don't have ant, on Windows do + +java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-simple-callback.jar simplecallback.SimpleCallbackClient + +and on *nix do + +java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-simple-callback.jar simplecallback.SimpleCallbackClient + + +Sample Overview +--------------- +The sample provides a single composite with two components. MyClientComponent is +wired to MyServiceComponent. The interface of MyServiceComponent describes one +method as ONEWAY and with a callback semantic. When a message passes from +client to service the response is returned via the callback asynchronously. + +simple-callback/ + src/ + main/ + java/ + simplecallback/ + MyClient.java - client interface + MyClientImpl.java - implements the client and service callback + interfaces + MyService.java - service interface + MyServiceCallback.java - service callback interface, implemented by the + client + MyServiceImpl.java - implements the service interface + SimpleCallbackClient.java - starts the SCA Runtime and + deploys the simplecallback.composite. + It then calls MyClientComponent which in turn + calls MyServiceComponent + resources/ + simplecallback.composite - the SCA assembly for this sample + wsdl/ + simplecallback.wsdl - the service description and callback binding + test/ + java/ + simplecallback/ + SimpleCallbackTestCase.java - JUnit test case + simple-callback.png - a pictorial representation of the sample + .composite file + build.xml - the Ant build file + pom.xml - the Maven build file + +Building And Running The Sample Using Ant +----------------------------------------- +With the binary distribution the sample can be built and run using Ant as +follows + +cd simple-callback-ws +ant compile +ant run + +You should see the following output from the run target. + +run: + [java] 14-Jan-2008 14:25:02 org.apache.tuscany.sca.http.jetty.JettyServer a +ddServletMapping + [java] INFO: Added Servlet mapping: http://L3AW203:8085/MyServiceCallbackCo +mponent + [java] 14-Jan-2008 14:25:02 org.apache.tuscany.sca.http.jetty.JettyServer a +ddServletMapping + [java] INFO: Added Servlet mapping: http://L3AW203:8085/MyServiceComponent + [java] Main thread Thread[main,5,main] + [java] aClientMethod on thread Thread[main,5,main] + [java] aClientMethod return from someMethod on thread Thread[main,5,main] + [java] setMyServiceCallback on thread Thread[pool-1-thread-2,5,main] + [java] someMethod on thread Thread[pool-1-thread-2,5,main] + [java] receiveResult on thread Thread[pool-1-thread-4,5,main] + [java] Result: -> someMethod -> receiveResult + + +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 simple-callback-ws +mvn + +You should see the following output from the test phase. + +------------------------------------------------------- + T E S T S +------------------------------------------------------- +Running simplecallback.SimpleCallbackTestCase +14-Jan-2008 14:26:28 org.apache.catalina.core.StandardEngine start +INFO: Starting Servlet Engine: Apache Tomcat/6.0.10 +14-Jan-2008 14:26:28 org.apache.catalina.startup.ContextConfig defaultWebConfig +INFO: No default web.xml +14-Jan-2008 14:26:28 org.apache.catalina.startup.DigesterFactory register +WARNING: Could not get url for /javax/servlet/jsp/resources/jsp_2_0.xsd +14-Jan-2008 14:26:28 org.apache.catalina.startup.DigesterFactory register +WARNING: Could not get url for /javax/servlet/jsp/resources/web-jsptaglibrary_1_ +1.dtd +14-Jan-2008 14:26:28 org.apache.catalina.startup.DigesterFactory register +WARNING: Could not get url for /javax/servlet/jsp/resources/web-jsptaglibrary_1_ +2.dtd +14-Jan-2008 14:26:28 org.apache.catalina.startup.DigesterFactory register +WARNING: Could not get url for /javax/servlet/jsp/resources/web-jsptaglibrary_2_ +0.xsd +14-Jan-2008 14:26:28 org.apache.catalina.startup.DigesterFactory register +WARNING: Could not get url for /javax/servlet/resources/j2ee_web_services_1_1.xs +d +14-Jan-2008 14:26:28 org.apache.coyote.http11.Http11Protocol init +INFO: Initializing Coyote HTTP/1.1 on http-8085 +14-Jan-2008 14:26:28 org.apache.coyote.http11.Http11Protocol start +INFO: Starting Coyote HTTP/1.1 on http-8085 +14-Jan-2008 14:26:28 org.apache.tuscany.sca.http.tomcat.TomcatServer addServletM +apping +INFO: Added Servlet mapping: http://L3AW203:8085/MyServiceCallbackComponent +14-Jan-2008 14:26:28 org.apache.tuscany.sca.http.tomcat.TomcatServer addServletM +apping +INFO: Added Servlet mapping: http://L3AW203:8085/MyServiceComponent +Main thread Thread[main,5,main] +aClientMethod on thread Thread[main,5,main] +aClientMethod return from someMethod on thread Thread[main,5,main] +Sleeping ... +setMyServiceCallback on thread Thread[pool-1-thread-1,5,main] +someMethod on thread Thread[pool-1-thread-1,5,main] +receiveResult on thread Thread[pool-1-thread-2,5,main] +Result: -> someMethod -> receiveResult +14-Jan-2008 14:26:31 org.apache.coyote.http11.Http11Protocol destroy +INFO: Stopping Coyote HTTP/1.1 on http-8085 +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 8.312 sec + +This shows that the Junit test cases have run successfully. |
