Providing a custom resolver for XML schemas

[Marco Zapletal]

Hi folks,

I would like to know how to provide a resolver for XSDs to my Web 
Service endpoints. One of our service requests include a reference to 
the XMLDSIG schema, which takes some time to resolve from w3.org.

I am aware of XML Catalogs and we use it at compile time for generating 
JAXB classes for our schemas. However, using XML Catalogs at runtime 
gave me a hard time so far. Moreover, there are now 3 copies of the 
XMLDSIG in our sources - one for generating the bindings, one for the 
integration tests using jetty and one for the schema validation at 
runtime when the services are deployed to tomcat.

Thus, I would like to know whether there is the possibility to plugin a 
custom resolver for the parser that is used under the hood similar to 
providing a custom LSResourceResolver to a JAXP validator.

Thanks,
Marco
