JAXB Naming Collision Salesforce Integration

I'm attempting to integrate with Sal开发者_开发问答esforce using MyEclipse. The wizard fails because of a naming collision on a complex type "DescribeLayout". I need to write a JAXB binding file to ensure that the two interfaces that are created by the xjc compiler are in different packages, but I have absolutely no idea how to do this.

I do not have the URI's to the schemas that make up the WSDL, only the URN's.

This blog post shows how to append a suffix to type names to avoid this. I'm not a JAXB expert, but presumably there is a way to configure it to use a different package instead of a suffix.
