Subject Re: Invoking external Web-Service results in SoapFault
Date Fri, 11 Sep 2009 00:12:32 GMT

I believe you have a namespaces conflict.

You initialized the "doSomethingPLRequest" variable with namespace
"http://example.ws" but refer to $doSomethingPLRequest.myinput
("><![CDATA[ns:myinput]]>) using xmlns:ns="http://test.webservices".

Try changing xmlns:xsd="http://example.ws" to
xmlns:xsd="http://test.webservices"

<bpel:process name="Caller"
         targetNamespace="http://MyTest.com/Test"
         suppressJoinFailure="yes"
         xmlns:tns="http://MyTest.com/Test"
        
xmlns:bpel="http://docs.oasis-open.org/wsbpel/2.0/process/executable"
         xmlns:ns="http://test.webservices">
......

        <bpel:assign validate="no" name="AssignInput">
            <bpel:copy>
                <bpel:from>
                    <bpel:literal xml:space="preserve"><xsd:doSomething
xmlns:xsd="http://example.ws">
  <xsd:myinput></xsd:myinput> 
</xsd:doSomething></bpel:literal>
                </bpel:from>
                <bpel:to part="parameters"
variable="doSomethingPLRequest"></bpel:to>
            </bpel:copy>
            <bpel:copy>
                <bpel:from part="payload" variable="input">
                    <bpel:query
queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[tns:input]]></bpel:query>
                </bpel:from>
                <bpel:to part="parameters" variable="doSomethingPLRequest">
                    <bpel:query
queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[ns:myinput]]></bpel:query>
                </bpel:to>
            </bpel:copy>
        </bpel:assign>
