    BPEL Problem with Fault Handler

    Fabiana Valandro Newbie

      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:

      <?xml version="1.0" encoding="UTF-8"?><wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:schema="http://www.xxx.it/xxx/schema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" targetNamespace="http://www.xxx.it/xxx/schema">

       </element>
      
       <element name="UnzipXPostFileResponse">
       <complexType>

       <element maxOccurs="1" minOccurs="0" name="nomeFileIndice" type="tns:TipoNomePathFile"/>

       </wsdl:port>
       </wsdl:service>
      </wsdl:definitions>
      


      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:

      11:31:20,107 WARN [ProxyWarnLog] Narrowing proxy to class org.jbpm.bpel.variable.def.MessageType - this operation breaks ==

      This is the fault message that I receive:
      <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
       <SOAP-ENV:Header/>
       <SOAP-ENV:Body>
       <SOAP-ENV:Fault>

       <faultstring>Server error</faultstring>

       </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,
