+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.
+
+To save space, the WAR file isn't included in the binary distribution. You can
+build it by following the instructions below in "Building And Running The Sample
+Using Ant" or "Building And Running The Sample Using Maven".
+
+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.
+
+Note: There can be a delay before a browser client receives a message typed into
+the chat. Some browsers receive pending messages immediately, some browsers
+receive pending messages when a new message is sent, and some browsers receive
+pending messages after a time delay of up to one minute.
+
+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.

+ WEB-INF/

+
+Building And Running The Sample Using Ant
+-----------------------------------------
+With the binary distribution the sample can be built using Ant as
+follows
+
+cd chat-webapp
+ant package
+
+This should result in a war file (sample-chat-webapp.war) in the target
+directory. Copy this war file to your web app deployment directory in you
+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-chat-webapp
+
+The port and hostname will of course vary depending on your local installation.
+
+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.
