topic TimerBoundaryEvent is not able to call Java service task in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/timerboundaryevent-is-not-able-to-call-java-service-task/m-p/158746#M112823 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I am trying to write a BPMN, which should invoke a service task(associated Java method) after the timer expires. I have specified "Time Duration" as "PT2M". But it is not getting invoked after time expires. </SPAN><BR /><BR /><SPAN>When I start a new process by executing the below command in Java, it make a entry in ACT_RU_JOB table which later gets updated as "Unknown method used in expression" in the EXCEPTION_MSG_ column.</SPAN><BR /><BR /><SPAN>runtimeService.startProcessInstanceByKey("resumeProcess", processInstance.getInpParam());</SPAN><BR /><BR /><SPAN>I tried number of options to get rid of this problem –</SPAN><BR /><BR /><SPAN>1) After this, in the attached BPMN if I remove the TimerBoundaryEvent, keeping service task as it is, it invokes my java method associated with service class without any issue, which means the expression I have defined for the service task is correct.</SPAN><BR /><BR /><SPAN>2) Instead of using the Spring annotation for my Java class, I defined it as a bean in the spring context file and mentioned the bean name in the expression of the service task. It still updated the ACT_RU_JOB-&gt;EXCEPTION_MSG_ column as "Unknown property used in expression"</SPAN><BR /><BR /><SPAN>3) Instead of calling the Receive Task(with TimerBouandaryEvent) from the StartEvent, I called TimeCatchingEvent from the StartEvent and </SPAN><BR /><SPAN>then from TimeCatchingEvent I called my service task. Still it was giving error message as "Unknown method used in expression".</SPAN><BR /><BR /><SPAN>I have attached the BPMN for the reference. I have spent almost 2 days on this, if someone can help me in finding the mistake which I am doing, it will be great.</SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>Rajat Gupta</SPAN></BODY></HTML> Thu, 24 Apr 2014 22:11:16 GMT rajatgupta1609 2014-04-24T22:11:16Z TimerBoundaryEvent is not able to call Java service task https://connect.hyland.com/t5/alfresco-archive/timerboundaryevent-is-not-able-to-call-java-service-task/m-p/158746#M112823 Hi,I am trying to write a BPMN, which should invoke a service task(associated Java method) after the timer expires.
