I was trying to make JBPM invoking web services, but failed... I first tried to use BPEL1.1 beta3, after integrating BPEL and jBPM into JBossAS respectively, I found that BPEL and jBPM were using different DBschema. How can I make them work together, e.g. let the business process invoke the web service deployed by BPEL? And then I tried to deploy a web service by using XFire, and it was successful and it also passed the test to test invoking this web service. However I tried to invoke it from the business process by doing: <action class="com.myService.xfireDemo.InvokeService"> When I actually invoke it when starting the business process, it shows an error message on the page: Error taking transition: com.myService.xfireDemo.InvokeService | The application received a org.jbpm.graph.def.DelegationException. | The message is: com.myService.xfireDemo.InvokeService Can anybody help with it?
