Hi, I am using :jboss-4.0.4.ga (server all). jbpm-bpel-1.1.Beta2 jbossws-1.0.3 Do you need any more information? The problem is that i think I have changed something else because I had some ERRORS. I have followed the steps in the user guide. ant deploy-process, ant generate-service , etc.... and then ant run-test If i had to begin from the scratch what should i install (and versions), in order to reproduce your environment ?
