-To execute sample webapp based contributions (contributions that have webapp at the end of their name) you

+The Tuscany SCA Java runtime can run inside a webapp (a WAR) and expose 
+services when the webapp is started. In order for this to work 
+a number of things have to be in place in the webapp:
 
-For example, for binding-jsonrpc/contribution-calculator-webapp, do the following
+1. The Tuscany runtime jars have to be packaed in the webapp WEB-INF/lib
+   directory
+2. The Tuscany HTTP filter servlet has to be configured in the 
+   WEB-INF/web.xml file using something like:
 
-cd samples/binding-jsonrpc/contribution-calculator-webapp
+  <filter>
+    <filter-name>tuscany</filter-name> 
+    <filter-class>org.apache.tuscany.sca.host.webapp.TuscanyServletFilter</filter-class> 
+  </filter>
+
+  <filter-mapping>
+    <filter-name>tuscany</filter-name> 
+    <url-pattern>/*</url-pattern> 
+  </filter-mapping>
+
+3. The composite application has to packaged in the WAR file. When the 
+   TuscanyServletFilter started it effectvely reads its own WAR file as
+   the contribution. As an alternative you can package complete 
+   contribution archives in the WEB-INF/sca-contributions directory.
+
+In the getting-started/helloworl-webapp sample we provided a Maven 
+build script that perform these WAR packaging steps.
