Hi,
do you have any further experience with this solution?
It works fine, but when I deploy and run it on jBoss, it seems that it doesn't when I call ksession.startProcess(processId, params); and within it it runs into my workitem handler in which I have taskSession.addTask(newTask, taskParameters);
It ends with exception You cannot commit during a managed transaction!
Did you get into similar problems?
