Incoming soap message not parsed

Question

From a BPEL process I invoke a web service deployed on the oc4j containers of JDev 9.0.4.
The SOAP message looks like this:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<ns1:invokeMethod soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
          xmlns:ns1="http://acm.org/samples">
<paramsXML xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:type="xsd:string">
          <Parameters>x<ParameterName></ParameterName><ParameterValue>y</ParameterValue></Parameters>
</paramsXML>
</ns1:invokeMethod>
</soapenv:Body>
</soapenv:Envelope>
The java class that implements the web service (it expects a String argument) gets an empty String instead of the contents of paramsXML above. What is going wrong?

Answer 1

If you want to use raw XML using xsd:string with an RPC-Encoded service developed using a java String as a parameter, you will have to encode your XML on the sender side.
The request should looks like this:
<?xml version = '1.0' encoding = 'UTF-8'?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://acm.org/samples">
<env:Body>
<ns0:invokeMethod env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<paramsXML xsi:type="xsd:string">
& l t ;Parameters>x& l t ;ParameterName>& l t ;/ParameterName>& l t ;ParameterValue>y& l t ;/ParameterValue>& l t ;/Parameters></paramsXML>
</ns0:invokeMethod>
</env:Body>
</env:Envelope>
note that the '<' are replaced by the '& l t ;' entity in the request {with extra space in the entity to render here}.
