> 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:
