Server using Provider implementation writes contents of SOAP body in SOAP header
--------------------------------------------------------------------------------
Key: CXF-4130
URL: https://issues.apache.org/jira/browse/CXF-4130
Project: CXF
Issue Type: Bug
Affects Versions: 2.5.2
Reporter: Seumas Soltysik
Fix For: 2.6
When using a server using a Provider implementation in conjunction with a WSDL
that defines a SOAP header as part of its output, the contents out the SOAP
body will be written as a SOAP header depending on the order of the parts
defined in the output message.
For example if an output message is defined like this:
<message name="FooResponse">
<part name="FooResponseHeader" element="tns:FooResponseHeader"/>
<part name="FooResponse" element="tns:FooResponse"/>
</message>
and the SOAP binding operation is defined like this:
<operation name="Foo">
<soap:operation/>
<input>
<soap:header message="tns:FooRequest"
part="FooRequestHeader" use="literal"/>
<soap:body parts="FooRequest" use="literal"/>
</input>
<output>
<soap:header message="tns:FooResponse"
part="FooResponseHeader" use="literal"/>
<soap:body use="literal"/>
</output>
</operation>
because the FooResponseHeader is defined as the first part in the output
message, CXF writes out the following message:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";>
<SOAP-ENV:Header>
<FooResponseHeader
xmlns:ns2="http://cxf.apache.org/soapheader/inband";>FooResponseHeader</FooResponseHeader>
<ns2:FooResponse xmlns:ns2="http://cxf.apache.org/soapheader/inband";>
<ns2:Return>Foo Response Body</ns2:Return>
</ns2:FooResponse></SOAP-ENV:Header>
<SOAP-ENV:Body/>
</SOAP-ENV:Envelope>
The basic reason for this is that the SoapOutInterceptor uses the part index of
the part defining the output header to look up the instance of that part in the
MessageContentList contained in the Message. However, in the Provider use case,
the MessageModeOutInterceptorInternal interceptor puts the contents of the SOAP
body into the first slot of the MessageContentList. So in the case where the
index of the SOAP header part is 0, the contents of the SOAP body get written
out as a SOAP header.
Additional details are available as part of the CXF developers mailing list
here:

A possible solution to this problem is to place the contents of the SOAP body
in the appropriate location in the MessageContentList in
MessageModeOutInterceptorInternal. This solution would look something like this:
MessageModeOutInterceptorInternal.handleMessage()
list.remove(0);
DocumentFragment frag =
soapMessage.getSOAPPart().createDocumentFragment();
try {
Node body = soapMessage.getSOAPBody();
Node nd = body.getFirstChild();
while (nd != null) {
body.removeChild(nd);
frag.appendChild(nd);
nd = soapMessage.getSOAPBody().getFirstChild();
}
int index = 0;
Exchange exchange = message.getExchange();
BindingOperationInfo operation =
(BindingOperationInfo)exchange.get(BindingOperationInfo.class
.getName());
List<MessagePartInfo> parts = null;
BindingMessageInfo bmsg = null;
boolean client = isRequestor(message);
if (!client) {
if (operation.getOutput() != null) {
bmsg = operation.getOutput();
parts = bmsg.getMessageParts();
}
} else {
bmsg = operation.getInput();
parts = bmsg.getMessageParts();
}
if (parts != null && parts.size() > 0) {
index = parts.get(0).getIndex();
}
list.set(index, frag);
