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-chat-webapp.war) +to your web application server. + +Once the web app is deployed use your browser to visit the following URL; + +http://localhost:8080/sample-chat-webapp + +The port and hostname will of course vary depending on your local installation. + +Sample Overview +--------------- +The sample provides an SCA component which has an SCA service using the SCA Ajax +binding and an SCA reference also using the Ajax binding. The component implementation +simply forwards every invocation of the service as an invocation on the reference. The +component reference is scoped by the composite so every active client of the composite +will receive every message sent to the component service, thus implementing the chat +application with very little code. + +chat-webapp/ + src/ + main/ + java/ + sample/ + ChatService.java - service interface + ChatServiceImpl.java - service implementation + resources/ + chat.composite - the SCA assembly for this sample + webapp + chat.html - the html UserInterface for this application + 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 + + pom.xml - the Maven build file + +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 chat-webapp +mvn + +Again this should result in a war file (sample-chat-webapp.war) in the target +directory. Follow the steps described in the previous section for running the web +app and for the expected results. + + diff --git a/sca-java-1.x/tags/0.91-incubating/samples/chat-webapp/pom.xml b/sca-java-1.x/tags/0.91-incubating/samples/chat-webapp/pom.xml new file mode 100644 index 0000000000..41987963ab --- /dev/null +++ b/sca-java-1.x/tags/0.91-incubating/samples/chat-webapp/pom.xml @@ -0,0 +1,67 @@ +<?xml version="1.0" encoding="UTF-8"?>
