XJB and JAXB binding on simpleType with same name

Question

I'm trying to generate JAVA code with jaxb and spring but I can't get it to work when I have as wsdl file with 2 simpleTypes with the same name but in different namespaces. Does anyone know how I can solve this?

I've been trying out the jaxb:factoryMethod tag but I can't get the syntax correct. But maybe there is a simpler way?

We have solved this now and it was the <generatePackage> element that was causing part of the problem. We also made sure to bind each schema/namespace to its own package. This way the ObjectFactory Classes won't complain.
