<div class="jive-rendered-content"><p>Hi, </p><p>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: </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>1. create the process instance:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><span><code>            logger.debug(">>> create a process instance");             ProcessInstance procInstance = ksession.createProcessInstance("test.TestComplete", params);</code></span><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>2. register transaction manager synchronization using Maciej's original CMTDisposeCommand  (in the afterCompletion method i dispose the ksession):</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre ___default_attr="html" class="jive_text_macro jive_macro_code"><p><code></p><p>            logger.debug(">>> register transaction synchronization");</p><p>            ksession.execute(new CMTDisposeCommand());</p> </code><br/></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>3. create and register a new class, CMTProcessEventListener, to listen for the process complete event (code attached below)</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre ___default_attr="html" class="jive_text_macro jive_macro_code"><p><code></p><p>            CMTProcessEventListener procEventListener = new CMTProcessEventListener(procInstance.getId(),ejbName);</p><p>            logger.debug(">>> add process events listener");</p><p>            ksession.addEventListener(procEventListener);</p><p> </code></p></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>4. start the process instance execution:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre ___default_attr="html" class="jive_text_macro jive_macro_code"><p><code></p><p>            logger.debug(">>> start the process instance");</p><p>            ksession.startProcess(procInstance.getProcessId());</p><p> </code></p></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thank you very much Jiri, hope this help someone else too.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Umberto</p></div>
