Lasantha, I've been trying to get this app to work on G 1.2. I updated the build script and deployment plans but still can't get the client to work. I had the same error in 1.1.1, any chance you could take a look at it?
Here is the link to the 1.2 version. http://cwiki.apache.org/GMOxDOC12/simple-web-services-sample-application.html Cheers! Hernan
