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?
