http://community.jboss.org/message/529862#529862 Author : Sean Mo Profile : http://community.jboss.org/people/seanmo Message: -------------------------------------------------------------- This happened on jBPM 4.0. Initially I defined a normal timer in my process definition, it worked well but after I changed it to a repeat timer (by adding repeat="30 seconds"), I encountered the following exception: Mar 4, 2010 5:40:35 PM org.jbpm.internal.log.Jdk14Log error SEVERE: exception while executing 'timer[23|2010-03-04 17:41:05,391|TimeoutEvent]' org.jbpm.api.JbpmException TimerImpl.java:150)at org.jbpm.pvm.internal.job.TimerImpl.execute( TimerImpl.java:52)at org.jbpm.pvm.internal.cmd.ExecuteJobCmd.execute( ExecuteJobCmd.java:74)at org.jbpm.pvm.internal.cmd.ExecuteJobCmd.execute( ExecuteJobCmd.java:41)at org.jbpm.pvm.internal.svc.DefaultCommandService.execute( DefaultCommandService.java:42)at org.jbpm.pvm.internal.spring.CommandTransactionCallback.doInTransaction( CommandTransactionCallback.java:50)at org.springframework.transaction.support.TransactionTemplate.execute( TransactionTemplate.java:128)at org.jbpm.pvm.internal.tx.SpringTransactionInterceptor.execute( SpringTransactionInterceptor.java:79)at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute( EnvironmentInterceptor.java:54)at org.jbpm.pvm.internal.svc.RetryInterceptor.execute( RetryInterceptor.java:55)at org.jbpm.pvm.internal.jobexecutor.JobExecutorThread.run( JobExecutorThread.java:63) Here's my timer definition: < custom expr=+"#{customWaitActivity}"+ name=+"Custom Wait"+ g=+"411,174,126,52"+> <on event=+"TimeoutEvent"+> <!--<timer duedate="30 seconds" />--> <timer duedate=+"30 seconds"+ repeat=+"30 seconds"+ /> <event-listener class=+"jbpm.demo.wf.spring.SpringEventListenerDelegate"+> <field name=+"beanName"+> <string value=+"timerExpireHandler"+ /> </field> </event-listener> </on> <transition name=+"timeout"+ to=+"Do Something"+ g=+"47,-8"+ > <timer duedate=+"7 business days"+></timer> </transition> </custom> Spring is used to control all the transactions in my project.
