Hello, I have an application which is using spring and jbpm 4.0. The application works fine if all the tasks are synchronous . But when I add an asynchronous task in between it is giving me Null pointerException in JobExecutorMessageSession.send. It seems like the transaction is not injected into the JobExecutorMessageSession. I have JobExecuter configured in my jbpm.cfg.xml <import resource="jbpm.jobexecutor.cfg.xml" /> and my spring config contain <bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration"> | <constructor-arg value="etc/jbpm.cfg.xml" /> | </bean> | <bean id="processEngine" factory-bean="jbpmConfiguration" factory-method="buildProcessEngine" lazy-init="false" /> I tried jbpm 4.0 but it it is also giving the same exception. Can anybody suggest what i am doing wrong... Regards, Joel View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4261387#...
