Hi,
M trying to integrate jBPM with Spring 3.0.3 but facing NullPointerException at *ProcessEngineImpl.checkDb(ProcessEngineImpl.java:152)*.
configuration files are attached.
The error originated at following line in ProcessEngineImpl which returns null.
*userCommandService = (CommandService) processEngineWireContext.get(CommandService.NAME_TX_REQUIRED_COMMAND_SERVICE);*
Please help.
Thanks
