[jira] Updated: (CXF-1003) WebFaultOutInterceptor.getFaultMessagePart() might be too draconian and it also has private visibility

["Zarar Siddiqi (JIRA)" <ji...@apache.org>]

Zarar Siddiqi updated CXF-1003:
-------------------------------

    Attachment: BetterCheckForAFaultMessagePartInfo.patch

I've submitted a patch which scans for a matching MessagePartInfo for a fault if the type's namespace didn't match.

To reproduce this issue all you have to do is the following:

package com.mycompany.services;
@WebService(targetNamespace="http://mycompany.com/MyService", ...)
public class MyService ... {
 public String doSomething() throws WebServiceException {...}
}

package com.mycompany;
@WebFault
public class WebServiceException extends Exception {
...
}

Then try calling it....

Thanks,
Zarar

> This implementation of this method is a little draconian (at least to me).  It forces a match on the localPart and the namespace of MessagePartInfo and the fault QName before returning the MessagePartInfo.  In the case of where the exception class annotated with @WebFault (default namespace so it "inherits" the services) is also the fault bean (i.e.: no getFaultInfo method specified) the name of the namespace URI will never match because only mpi's that are NOT elements are going to be considered.   And since the fault class is a java class, it's corresponding MPI's getTypeQName() will always return the namespace corresponding to the package name and NOT the real namespace of the exception (which really lies behind getElementQName()).
> I propose changing this method so that if no MessagePartInfo is found using the current method, we loosen the criteria and return a match based on  the elementQName.  This will also require modification of the MessagePartInfo class.  
> Now the alternate is to make this method public or protected so it can be overridden.  But that's not really a solution.
> I'm working on a patch but before I upload it I was wondering what the CXF team thought of this
> Thanks,

> Here's the method up for review:
> private MessagePartInfo getFaultMessagePart(QName qname, OperationInfo op) {
> 	for (FaultInfo faultInfo : op.getFaults()) {
> 		for (MessagePartInfo mpi : faultInfo.getMessageParts()) {
> 			String ns = null;
> 			if (mpi.isElement()) {
> 				ns = mpi.getElementQName().getNamespaceURI();
> 			} else {
> 				ns = mpi.getTypeQName().getNamespaceURI();
> 			}
> 			if (qname.getLocalPart().equals(mpi.getConcreteName().getLocalPart())
> 					&& qname.getNamespaceURI().equals(ns)) {
> 				return mpi;
> 			}
> 		}
> 	}
