Hi Sam,
Thanks for your reply. My issues happened in SOA-P platform. i.e. the jbpm-ds.xml is in jbpm.esb folder. I am sure jbpmDS is enabled because the jbpm console is up and running without any problem. Just if my application is deployed at deploy folder, my application cannot find java:/jbpmDS datasource. But if my application is deployed in jbpm.esb folder, it works fine. Do you have any clues or why?
Thanks
