Question

I have a service proxy set up and I am able to view the wsdl, but when I try to test it using soapUI it almost seems to timeout. I’ll post the mule config, and both the soapUI log, and mule studio log. When I hit the wdsl normally without a proxy, it is a quick response.

Google results don’t seem to produce much, so any guidance on the source, soapUI or Mule, and the issue would be helpful.

Mule Flow

<flow name="UPCFlow1" doc:name="UPCFlow1">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="4040" path="upc" doc:name="HTTP" contentType="text/xml" mimeType="text/xml"/>

    <cxf:proxy-service namespace="http://searchupc.com/" service="UPCSearch" payload="envelope" wsdlLocation="http://www.searchupc.com/service/UPCSearch.asmx?WSDL"  doc:name="SOAP" enableMuleSoapHeaders="false"/>
<http:outbound-endpoint address="http://www.searchupc.com/"
    exchange-pattern="request-response" doc:name="HTTP" contentType="text/xml" mimeType="text/xml"/>
</flow>

Answer 1

There were several issues:

• Wrong address of the remote web service,
• Missing cxf:proxy-client element,
• Lack of copying SOAPAction over (if not using SOAP 1.2).

Below is the fixed example for SOAP 1.1. Note that I have placed the CXF elements inside the endpoints: this is not a requirement (they could be directly in the flow), but just the usual way of placing them in the configuration.

<flow name="UPCFlow1">
    <http:inbound-endpoint exchange-pattern="request-response"
        host="localhost" port="4040" path="upc">
        <cxf:proxy-service namespace="http://searchupc.com/"
            service="UPCSearch" payload="body"
            wsdlLocation="http://www.searchupc.com/service/UPCSearch.asmx?WSDL"
            enableMuleSoapHeaders="false" />
    </http:inbound-endpoint>
    <copy-properties propertyName="SOAPAction" />
    <http:outbound-endpoint
        address="http://www.searchupc.com/supc/service/UPCSearch.asmx"
        exchange-pattern="request-response" method="POST">
        <cxf:proxy-client payload="body" />
    </http:outbound-endpoint>
</flow>

And for SOAP 1.2:

<flow name="UPCFlow1">
    <http:inbound-endpoint exchange-pattern="request-response"
        host="localhost" port="4040" path="upc">
        <cxf:proxy-service namespace="http://searchupc.com/"
            service="UPCSearch" payload="body"
            wsdlLocation="http://www.searchupc.com/service/UPCSearch.asmx?WSDL"
            enableMuleSoapHeaders="false" />
    </http:inbound-endpoint>
    <http:outbound-endpoint
        address="http://www.searchupc.com/supc/service/UPCSearch.asmx"
        exchange-pattern="request-response" method="POST">
        <cxf:proxy-client payload="body" soapVersion="1.2" />
    </http:outbound-endpoint>
</flow>
