    executing process with timer

    Aziz Boxwala Newbie

      I am encountering an error trying to execute a process that has a timer. I am running jbpm 3.2.1 in its app-server form, using the ear file, on jboss AS 4.2.1.GA.

      The only change we made in the ear was to modify the hibernate config file since we switched the DBMS to MSSQL 2005. That seems to work okay when we execute processes without timer.

      However, in trying to execute a process with timer, there is an issue with the TimerServiceBean not being found. I understand from the documentation that the jbpm-enterprise.jar includes the deployment descriptors for JBoss AS. Did I miss a configuration step in setting up ejb/LocalTimerEntityBean?
