[jboss-user] [JBoss jBPM] - Re: How to use faultVariable in fault handler?

[jiehuan_li]

Alex,

Thanks for the reply.  I tried defining the variable in the enclosing scope and then referencing it in the faultHandler by faultVariable, but I ran into a dilemma.  If I try to deploy the definition with the faultVariable specified in the faultHandler, I am getting the following exception:


  | 10:05:41,967 ERROR [[DeployServlet]] Servlet.service() for servlet DeployServlet threw exception
  | org.jbpm.jpdl.JpdlException: [[ERROR] jbpmbpel.bpel catch must specify either a faultMessageType or a faultElement [/process/faultHandlers/catch]]

Then I added 'faultElement' in the 'catch', I am getting the following exception:

Below is my code:

  |   </variables>
  | <faultHandlers>
  |        <catch faultName="svc:JSR181WebServiceException" faultVariable="svcFlt">
  |             <sequence>
  |        		<assign name="copyStep2Fault">
  |       			<copy>
  |         			<from variable="svcFlt" query="/JSR181WebServiceException/svc:code"/>
  |         			<to variable="operationFlt" part="detail"/>
  |       			</copy>      
  | 		</assign>
  |             <reply operation="connect2" partnerLink="jbpmbpelRelation" portType="jbpmbpel:jbpmbpelFrontEnd"
  |                       variable="operationFlt" faultName="jbpmbpel:step2Fault" />
  |             </sequence>
  |        </catch>
  |   </faultHandlers>
  | </process>
  | 

I understand that adding 'faultElement' in catch causes problem because bpel 1.1 schema doesn't allow it, but why do I get the first exception when I don't have faultElement or faultMessageType in catch?
