    Why are these complex types not compatible?

    akh2103
      In simple Java OO terms: I have one web service that returns an array of integers. I have another web service that accepts an array of integers. I want to feed the output from one webservice into the input of the other web service.

      In WSDL/BPEL terms...

      Service #1's operation personPositionInfoResponse, returns an array of integers as a complex type:

      <wsdl:message name="personPositionInfoResponse">
      <wsdl:part name="parameters" element="ns:personPositionInfoResponse"/>
      </wsdl:message>

      <xs:element name="personPositionInfoResponse">
      <xs:complexType>
      <xs:sequence>
      <xs:element minOccurs="0" name="return" type="xs:int"/>
      </xs:sequence>
      </xs:complexType>
      </xs:element>
      Position Skill Management takes an array of integers as input:

      Service #2's positionSkillRequest takes a complex type that is an array of integers as input:

      <wsdl:message name="positionSkillRequest">
      <wsdl:part name="parameters" element="ns:positionSkill"/>
      </wsdl:message>

      <xs:element name="positionSkill">
      <xs:complexType>
      <xs:sequence>
      <xs:element minOccurs="0" name="positionID" type="xs:int"/>
      </xs:sequence>
      </xs:complexType>
      </xs:element>

      Here is the code that tries to assign the variables:

      This is my best idea so far:

      <bpel:copy>
      <bpel:from>
      <![CDATA[$personalInfoServiceOutput.parameters]]>
      </bpel:from>
      <bpel:to >
      <![CDATA[$positionSkillManagementInput.parameters]]>
      </bpel:to>
      </bpel:copy>

      which returns...

      The from-spec of "<xs:complexType>" is not compatible with to-spec of "<xs:complexType>" - Element <ns:return> in httplocalhost...:8080/axis2/services/PersonalInfoService?wsdl differs from <ns:positionID> in httplocalhost...:8080/axis2/services/PositionSkillManagementService?wsdl different QNames: ns:return vs ns:positionID

      What can I do?
