Hi,
I'm not able to define an exeption-handler that handle Exception included inside the process archive. I'm using jbpm 3.2.6SP1 with jboss 5.0.1 and jboss 4.2.3.
That's the problem:
Using JBPM console I deploy a process archive with this process definition:
| <?xml version="1.0" encoding="UTF-8"?>
| <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="testException">
| <start-state name="start">
| <transition to="state1"></transition>
| <event type="node-leave">
| <script name="sysout">
| java.lang.System.out.println("---STARTING PROCESS testException--- ");
| </script>
| </event>
| </start-state>
| <state name="state1">
| <transition to="end-state">
| <action name="ThrowMyException" class="com.sample.action.ThrowMyExceptionActionHandler"></action>
| </transition>
| </state>
| <end-state name="end-state">
| <event type="node-enter">
| <script name="sysout">
| java.lang.System.out.println("---END PROCESS testException--- ");
| </script>
| </event>
| </end-state>
| <exception-handler exception-class="com.sample.action.MyException">
| <action name="exceptionHandler"
| class="com.sample.action.MyExceptionHandler">
| </action>
| </exception-handler>
| </process-definition>
|
When the execution enter "state1" i can see that:
- com.sample.action.ThrowMyExceptionActionHandler is entered
- This action is empty, it only throws a com.sample.action.MyException-
- com.sample.action.MyExceptionHandler is not reached and JBPMConsole report this error:
Error signalling token: An exception of type "org.jbpm.JbpmException"
was thrown. The message is: class not found 'com.sample.action.MyException'
If i change the exception-class with java.lang.Exception inside the excpetion-handler the exception will be correctly caught and the process execution finish without problems.
| <exception-handler exception-class="java.lang.Exception">
| <action name="exceptionHandler"
| class="com.sample.action.MyExceptionHandler">
| </action>
| </exception-handler>
|
I don't experience this problem if i try this process with a simple JUnit test case.
Am i doing something wrong?
Thanks
Max
