[jboss-user] [JBoss jBPM] - jbpm bpel problem with doc/lit format.

Mon Aug 21 05:42:53 EDT 2006

wrote a simple bpel code:

<?xml version="1.0" encoding="UTF-8"?>
<process name="review" targetNamespace="urn:author"
  xmlns:urn="urn:author"
  xmlns:rev="urn:reviewer"
  xmlns:bpel="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://schemas.xmlsoap.org/ws/2003/03/business-process/
                      http://schemas.xmlsoap.org/ws/2003/03/business-process/"
  xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/">

    <!-- realizes the abstract relationship with the caller -->

    <!-- realizes the relationship with the reviewer1 -->

    <!-- holds the incoming message -->

    <!-- holds the outgoing message -->

    <!-- receive a message carrying the name of a person -->

    <!-- reply with a message carrying the greeting -->

the corresponding wsdl is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="urn:author"
  xmlns:urn="urn:author"
  xmlns:rev="urn:reviewer"
  xmlns="http://schemas.xmlsoap.org/wsdl/"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:plt="http://schemas.xmlsoap.org/ws/2003/05/partner-link/"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <!-- characterizes the relationship between the process and its caller -->
  <plt:partnerLinkType name="callerPLT">
    <plt:role name="service">
      <plt:portType name="urn:callerPT"/>
    </plt:role>
  </plt:partnerLinkType>

 <plt:partnerLinkType name="reviewPLT">
    <plt:role name="review">
      <plt:portType name="rev:Reviewer"/>
    </plt:role>
 </plt:partnerLinkType>

  <!-- describes the interface presented to callers-->

the rev.wsdl of the external web service used is as follows:

<?xml version="1.0" encoding="UTF-8"?>

<wsdl:definitions targetNamespace="urn:reviewer"
xmlns:apachesoap="http://xml.apache.org/xml-soap"
xmlns:impl="urn:reviewer"

            <!--encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="urn:reviewer" -->
         </wsdl:input>
         <wsdl:output name="reviewResponse">

   <wsdl:service name="ReviewerService">
      <wsdl:port binding="impl:reviewerSoapBinding" name="reviewer">
         <wsdlsoap:address location="http://localhost:8080/reviewer/reviewer"/>
      </wsdl:port>
   </wsdl:service>
</wsdl:definitions>

in the "binding.xml" generated after generate-artifacts, the style has been changed to document/literal. the web-service involved also supports doc/lit format. 

the bpel process gets deployed. using wsdl2Java, the client is generated. i get the following error:
