+Chat WebApp Sample
+==================
+This sample demonstrates the SCA DWR binding to implement the classic Ajax sample
+of a chat application which allows multiple users to chat from their browsers.
+
+The README in the samples directory (the directory above this) provides 
+general instructions about building and running samples. 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 DWR
+binding and an SCA reference also using the DWR 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.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.
