Mon Aug 21 06:08:28 EDT 2006

sorry guys, some prob with my machine...neways the following is the bpel process:

<!--
<?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 -->
    partnerLink name="caller" partnerLinkType="urn:callerPLT" myRole="service"/>

    <!-- realizes the relationship with the reviewer1 -->
    partnerLink name="reviewer1" partnerLinkType="urn:reviewPLT" partnerRole="review"/>

  /partnerLinks>

  variables>
    <!-- holds the incoming message -->
    variable name="request" messageType="rev:reviewRequest"/>
    variable name="request1" messageType="rev:reviewRequest"/>
    <!-- holds the outgoing message -->
    variable name="response" messageType="rev:reviewResponse"/>
    variable name="response1" messageType="rev:reviewResponse"/>
  /variables>

  sequence>
    !-- receive a message carrying the name of a person -->
    receive operation="reviewRequest" partnerLink="caller" portType="urn:callerPT"
     variable="request" createInstance="yes"/>

	assign name="copy1">
		 copy>
			 from variable="request"/>
			 to variable="request1"/>
		 /copy>
	/assign>

    invoke operation="review" partnerLink="reviewer1" portType="rev:Reviewer"
      inputVariable="request1" outputVariable="response1">
    /invoke>

    assign name="copy2">
		 copy>
			 from variable="response1"/>
			 to variable="response"/>
		/copy>
  	/assign>

    <!-- reply with a message carrying the greeting -->
    reply operation="reviewRequest" partnerLink="caller" portType="urn:callerPT"
     variable="response"/>

  /sequence>

/process>
-->

please disregard the tags...it was not gettin uploaded otherwise..
the wsdl associated with the ablove bpel process 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">

import namespace="urn:reviewer" location="interface/rev.wsdl" />

  <!-- 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-->
  portType name="callerPT">
    operation name="reviewRequest">
      input message="rev:reviewRequest"/>
      output message="rev:reviewResponse"/>
    /operation>
  /portType>

/definitions>

the rev.wssdl imported above is also given below:

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

         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:
