Subject [jira] Created: (CXF-1996) NPE on JAXWS service initialization
Date Thu, 22 Jan 2009 09:57:59 GMT
NPE on JAXWS service initialization
-----------------------------------

                 Key: CXF-1996
                 URL: https://issues.apache.org/jira/browse/CXF-1996
             Project: CXF
          Issue Type: Bug
          Components: JAX-WS Runtime
    Affects Versions: 2.1.3
         Environment: Platform independent bug
            Reporter: Richard Opalka
             Fix For: 2.1.4


We're getting the below NPE with CXF 2.1.3.
It is related to CXF internal initialization.
The problematic code is in ReflectionServiceFactoryBean in method

protected boolean initializeClassInfo(OperationInfo o, Method method, List<String> paramOrder)
{
   if (isWrapped(method)) {
      if (o.getUnwrappedOperation() == null) {
         //the "normal" algorithm didn't allow for unwrapping,
         //but the annotations say unwrap this.   We'll need to
         //make it.
         WSDLServiceBuilder.checkForWrapped(o, true); // Inside of this code RULE no.2 fails
and thus unwrapper operation isn't set at all
      }
      ...
      o = o.getUnwrappedOperation(); // HERE the o variable is set to NULL
   } else if (o.isUnwrappedCapable()) {
      ...
   }
   o.setProperty(METHOD_PARAM_ANNOTATIONS, method.getParameterAnnotations()); // HERE we're
getting NPE because o was set to null
   ...
}

We're attaching also web service archive to reproduce the problem.
This is the exception we're facing:
