Hi Ruwan, thank you for your help. I now have this Synapse configuration:
<definitions xmlns="http://ws.apache.org/ns/synapse";> <localEntry key="validateCli.wsdl" src="file:/c:/dev/synapse-1.2/harness/validateCli.wsdl"/> <localEntry key="ValidateCLIRequest" src="file:/c:/dev/synapse-1.2/harness/ValidateCLIRequest_V1.0.xsd"/> <localEntry key="ValidateCLIResponse" src="file:/c:/dev/synapse-1.2/harness/ValidateCLIResponse_V1.0.xsd"/> <localEntry key="CommonTypes" src="file:/c:/dev/synapse-1.2/harness/commontypes.xsd"/> <proxy name="ValidateCLI" transports="http" trace="enable"> <publishWSDL key="validateCli.wsdl" trace="enable"> <resource location="ValidateCLIRequest_V1.0.xsd" key="ValidateCLIRequest"/> <resource location="ValidateCLIResponse_V1.0.xsd" key="ValidateCLIResponse"/> <resource location="commontypes.xsd" key="CommonTypes"/> </publishWSDL> <parameter name="useOriginalwsdl">true</parameter> <parameter name="modifyUserWSDLPortAddress">true</parameter> <target> <inSequence> <send> <endpoint> <address uri=" http://server_name_hidden/ValidateCLI/TelewestBindingPort"/> </endpoint> </send> </inSequence> <outSequence> <send/> </outSequence> </target> </proxy> </definitions> which still gives me and empty response body and a 202 Accepted. Synapse logs do not show any exceptions or problems, as far as I can see. Any suggestions? Could my problems be related to the fact that my webservice endpoint stubs have been generated with Sun's 'wsimport' instead of the Axis' 'wsdl2java? Should I perhaps not include the binding port and/or the service name in the URL? After a week, I'm still pretty stuck here, attempting to proxy this web service :-) Any suggestions would be very (very) welcome! Many thanks!
