Hi, I did the following after which it started working a)no change in build.xml b) i was having two datasources, oracle-ds and derby-ds. I deleted the oracle-ds, and put the hsqldb-ds.xml(provided by jboss by default). c)deleted all ejb jar in deploy folder d)deleted tmp and work folder and restart the server made it as though it is new jboss server after that ran the same build, it started working..i am not sure which of the one above solved the problem Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4205715#...
