"Re: timer job issues when disposing session in embedded j2ee process" To view the discussion, visit: https://community.jboss.org/message/824964#824964 -------------------------------------------------------------- Hi, ok, i've found a solution. In my EJB project, in the method exposed, i create a knowledge session per call, and a single process instance: 1. create the process instance: logger.debug(">>> create a process instance"); ProcessInstance procInstance = ksession.createProcessInstance("test.TestComplete", params); 2. register transaction manager synchronization using Maciej's original CMTDisposeCommand (in the afterCompletion method i dispose the ksession): <code> logger.debug(">>> register transaction synchronization"); ksession.execute(new CMTDisposeCommand()); </code> 3. create and register a new class, CMTProcessEventListener, to listen for the process complete event (code attached below) <code> CMTProcessEventListener procEventListener = new CMTProcessEventListener(procInstance.getId(),ejbName); logger.debug(">>> add process events listener"); ksession.addEventListener(procEventListener); </code> 4. start the process instance execution: <code> logger.debug(">>> start the process instance"); ksession.startProcess(procInstance.getProcessId()); </code> 5. at this point, i've implemented a cycle in my code to wait until the procEventListener.isProcessCompleted() is true before terminate the ejb method. The jBPM engine notify the CMTProcessEventListener after the process complete, timer included, the EJB method ends so the ejb container commits the transaction and call the afterCompletion method so i can dispose che session. Thank you very much Jiri, hope this help someone else too.
