Subject [jira] Created: (AXIS2-3634) NullPointerException during codegen when using JaxB RI databinding

NullPointerException during codegen when using JaxB RI databinding
------------------------------------------------------------------

                 Key: AXIS2-3634
                 URL: https://issues.apache.org/jira/browse/AXIS2-3634
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: codegen
    Affects Versions: 1.3, 1.4
         Environment: Windows XP, Java 6
            Reporter: Aaron Gourley


I was able to get around the following exception by replacing org.apache.axis2.jaxbri.CodeGenerationUtility
line 125 of Axis2 1.4 RC1 as follows (in anonymous EntityResolver.resolveEntity())

Replace this: if (key.getTargetNamespace().equals(publicId)) {
With this: if (key.getTargetNamespace() != null && key.getTargetNamespace().equals(publicId))
{

Additionally, I'm not sure if it would be acceptable to skip the for loop all together if
publicId is null.

The exception that I encountered was:

I will attach a WSDL that exploits this issue and the WSDL2Java parameters used.
