    BPEL Problem: Fault Handler

    agusgr Nov 7, 2007 6:30 AM

      Hi, I'm trying to develop a BPEL process with fault handling. I have a DNS web service wich send a fault message when cannot resolve an URL. The wsdl from this service is this:

      <?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://dns"
xmlns:apachesoap="http://xml.apache.org/xml-soap"
xmlns:impl="http://dns" xmlns:intf="http://dns"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<!--WSDL created by Apache Axis version: 1.3
Built on Oct 05, 2005 (05:23:37 EDT)-->
 <wsdl:types>
 <schema elementFormDefault="qualified"
targetNamespace="http://dns" xmlns="http://www.w3.org/2001/XMLSchema">
 <element name="getIPByURL">
 <complexType>
 <sequence>
 <element name="request" type="impl:DNSRequestData"/>
 </sequence>
 </complexType>
 </element>
 <complexType name="DNSRequestData">
 <sequence>
 <element name="URL" nillable="true" type="xsd:string"/>
 </sequence>
 </complexType>
 <element name="getIPByURLResponse">
 <complexType>
 <sequence>
 <element name="getIPByURLReturn" type="impl:DNSResponseData"/>
 </sequence>
 </complexType>
 </element>
 <complexType name="DNSResponseData">

 </wsdl:types>

 <wsdl:message name="getIPByURLRequest">

 <wsdl:part element="impl:getIPByURL" name="parameters"/>

 </wsdl:message>

 <wsdl:message name="DNSFault">

 <wsdl:part element="impl:fault" name="fault"/>

 </wsdl:message>

 <wsdl:message name="getIPByURLResponse">

 <wsdl:part element="impl:getIPByURLResponse" name="parameters"/>

 </wsdl:message>

 <wsdl:portType name="DNS">

 <wsdl:operation name="getIPByURL">

 <wsdl:input message="impl:getIPByURLRequest" name="getIPByURLRequest"/>

 <wsdl:output message="impl:getIPByURLResponse" name="getIPByURLResponse"/>

 <wsdl:fault message="impl:DNSFault" name="DNSFault"/>

 </wsdl:operation>

 </wsdl:portType>

 <wsdl:binding name="DNSSoapBinding" type="impl:DNS">

 <wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

 <wsdl:operation name="getIPByURL">

 <wsdlsoap:operation soapAction=""/>

 <wsdl:input name="getIPByURLRequest">

 <wsdlsoap:body use="literal"/>

 </wsdl:input>

 <wsdl:output name="getIPByURLResponse">

 <wsdlsoap:body use="literal"/>

 </wsdl:output>

 <wsdl:fault name="DNSFault">

 <wsdlsoap:fault name="DNSFault" use="literal"/>

 </wsdl:fault>

 </wsdl:operation>

 </wsdl:binding>

 <wsdl:service name="DNSService">

 <wsdl:port binding="impl:DNSSoapBinding" name="DNS">

 <wsdlsoap:address location="http://localhost:4040/DNSWebService/services/DNS"/>

 </wsdl:port>

 </wsdl:service>

</wsdl:definitions>

      In the BPEL code I have this:
      <bpws:faultHandlers>
 <bpws:catch faultName="ns1:DNSFault">
 <bpws:sequence name="HiddenSequence">
 <bpws:assign name="LoadErrorMessage" validate="no">
 <bpws:copy>
 <bpws:from>'Error in Service'</bpws:from>
 <bpws:to>$output.outputparam/tns:City</bpws:to>
 </bpws:copy>
 <bpws:copy>
 <bpws:from>'Error in Service'</bpws:from>
 <bpws:to>$output.outputparam/tns:Country</bpws:to>
 </bpws:copy>
 </bpws:assign>
 <bpws:reply name="SendErrorMessage" operation="getURLInfo" partnerLink="client" portType="tns:BPELService" variable="output"/>
 </bpws:sequence>
 </bpws:catch>
 </bpws:faultHandlers>

      The proces is deployed and works well when there is no fault, but when the DNS service send a fault message, I got this:
      2007-11-07 12:14:18,234 DEBUG [org.jbpm.bpel.integration.jms.StartListener] caught exception while passing control to process, searching for handler

      The fault message that I receive is this:
      <soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
      <soapenv:Header/>
      <soapenv:Body>
      <env:Fault xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
      <faultcode>soapenv:Server.generalException</faultcode>
      <faultstring></faultstring>
      <detail>
      <ns1:exceptionName xmlns:ns1='http://xml.apache.org/axis/'>dns.DNSFault</ns1:exceptionName>
      <ns2:hostname xmlns:ns2='http://xml.apache.org/axis/'>medea</ns2:hostname>
      </detail>
      </env:Fault></soapenv:Body></soapenv:Envelope>

      I'm using the JBoss AS 4.05 and the BPEL engine jbpm-bpel.1.1.Beta3. To develop the DNS web service I use the Eclipse WTP 3.2 version.
      I think that the fault message is not correct, but I don't know well what kind of fault messages expects the bpel engine.
      Any ideas??

      Thank you all and sorry for the long post
