    Persistence for jbpm5 in Tomcat 7 problem

    process15
    process15 Feb 17, 2012 8:48 AM

      Hi

       

      I've previously managed to setup jbpm 5 with persistence in a J2SE application but I'm now trying to convert and deploy my app as a servlet on a tomcat. I'm using Eclipse dynamic web project to create the servlet.

       

      My problem is that tomcat can't seem to find my "datasource: jdbc/testDS1". I've followed the user guide's instruction on persistence.xml etc (works in J2SE mode). I'm suspecting that I've misconfigured Tomcat somewhere.

       

      This is the error I get:
