How to resolve xsd:import in wsdl files

[mathertel]

I want to load a wsdl generated for a web service by calling the url
Calc?wsdl.
This WSDL definition contains xsd:import statements that point to the
separated schema that I can see when calling Calc?xsd=1.

1. How can I load the wsdl definition including the definition of the
schema into a XMLDocument ?
2. Or can I tell JAX-WS not to split the WSDL definition ?

Any help is welcome - I am stuck.
btw: I am working with Java 1.5 / JAX-WS 2.0 / Netbeans 5.5
