I am evaluating the compatibility of jBPM to work in other application server
environments. Actual i am on testing in weblogic (8.0, 9.0, 9.2).
It works in all versions perfectly, except the timer functionality.
In 8.0 no TimedObject.class exists, so it has to be done i an other way )-:
In 9.0 and 9.2 The timers are created in db, but at the execution date (duedate) an
exception is thrown:
