    Failure instantiating custom ActionHandler

    Chip Schoch Novice

      JBossAs 4.2.2.GA, jpdl 3.2.2

      Each time try to run my process it cannot load my action class. Looking at it in the debugger and it is trying to load it from the db. I included the action classes in a jar in the service archiveI deployed, not in the process definition. (Although when I added it to the process definition deployer it did not instantiate it either).

      I am not how to proceed. It used to work and now it doesn't and I don't know why.
