+Hello World Dojo RPC Sample
+===========================
+This sample demostrates the SCA JSONRPC binding using a simple web app that
+uses the RPC support of the Dojo Toolkit to an SCA service.  
+
+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-helloworld-dojo.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-dojo
+
+The port and hostname will of course vary depending on your local installation. 
+
+See also the similar helloworld-jsonrpc sample which also uses the SCA JSONRPC binding
+but uses SCA scaDomain.js script on the client instead of the Dojo Toolkit. 
+
+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 Dojo Toolkit JSON-RPC support can be 
+used to invoke the SCA service. 
+
+The web app provided shows how the service can be called by using the DOJO toolkit.

+                                        sample build process to download the Dojo Toolkit 
+                                        and get it included in the WAR file 
+                                        for use by the sample.

+
+Building And Running The Sample Using Ant
+-----------------------------------------
+With the binary distribution the sample can be built using Ant as 
+follows
+
+cd helloworld-dojo
+ant package
+
+This should result in a war file (sample-helloworld-dojo.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-dojo
+
+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-dojo 
+mvn
+
+Again this should result in a war file (sample-helloworld-dojo.war) in the target 
+directory. Follow the steps described in the previous section for running the web 
+app and for the expected results.
