Schema Loading Question

I am using Xerces to load schemas that are described in WSDLs.  Below is a representation:

 

<wsdl:definition>

<wsdl:types>

 

<xs:schema targetNamespace="a">

<xs:import namespace="b"/>

</xs:schema>

<xs:schema targetNamespace="b">

<xs:import namespace="a"/>

</xs:schema>

 

</wsdl:types>

</wsdl:definition>

   

Note that there are 2 schemas and they reference each other via import.

 

So here is my problem.  When I load the schema "a" using XMLSchemaLoader.loadGrammar(XMLInputSource), Xerces tells me that it cannot resolve the types that are defined in schema "b".  Likewise, if I try to load schema "b" first, then Xerces cannot resolve types defined in schema "a".

 

If I save these inline schemas in WSDLs to a file and add the correct schemaLocation attribute to the import element, Xerces loads the schemas fine. 

 

My question is: is there a way to load these schemas (without having to save them to file and adding the schemaLocation attribute) in a way that Xerces can resolve the types properly?  I have access to these schemas in memory (as org.w3c.dom.Node).

 

Any help is much appreciated!
