[JBoss jBPM] - BPEL Problem with Fault Handler - jbpm-users

Monday, 18 August 2008

Hi, I'm trying to develop a BPEL process with fault handling. I have a web service
wich unzip a file and send a fault message when cannot find the file. The wsdl of this web
service is this:

In the BPEL code I have this inline fault handler:

  |         <bpws:invoke inputVariable="unzipXPostFileRequest"
name="Invoke"
  |             operation="UnzipXPostFile"
  |             outputVariable="unzipXPostFileResponse"            
  |             partnerLink="xPostWS" portType="ns0:XPostWS">
  |             <bpws:catch faultMessageType="ns0:UnzipXPostFileFault"
  |                 faultName="ns0:UnzipXPostFileFault"
faultVariable="unzipXPostFileFault">
  |                 <bpws:sequence>
  |                     <bpws:assign name="Assign2"
validate="no">
  |                         <bpws:copy>
  |                             <bpws:from><![CDATA[concat($input.payload,
"Errore")]]></bpws:from>
  |                             <bpws:to part="payload"
variable="input">
  |                                 <bpws:query
queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[tns:input]]></bpws:query>
  |                             </bpws:to>
  |                         </bpws:copy>
  |                     </bpws:assign>
  |                 </bpws:sequence>
  |             </bpws:catch>
  |         </bpws:invoke>
  | 

The process is deployed and works well when there is no fault, but when the service send a
fault message, I got this:

This is the fault message that I receive:

  |    <SOAP-ENV:Header/>
  |    <SOAP-ENV:Body>
  |       <SOAP-ENV:Fault>
  |          <faultcode>SOAP-ENV:Server</faultcode>
  |          <faultstring>Server error</faultstring>
  |          <detail>
  |             <UnzipXPostFileFault
xmlns="http://www.xxxx.it/xxxx/schema">
  |                <customField>100</customField>
  |             </UnzipXPostFileFault>
  |          </detail>
  |       </SOAP-ENV:Fault>
  |    </SOAP-ENV:Body>
  | </SOAP-ENV:Envelope>
  | 

I'm using the JBoss 4.2.2.GA  and the BPEL engine jbpm-bpel.1.1.GA To develop the web
service I use Spring Web Services (first contract). 
Any ideas?
Thank you all and sorry for the long post,
Fabiana
