Hi, I'm having some trouble with JAXP and Schema validation. Basically I want to parse in XML files that can us a DTD or Schema (for example web.xml, depending on the version it is a DTD or Schema). The main problem is that the XML file refers to external entities that must be resolved so that the file can be parsed on a different system then it was written on. For DTDs this is not that difficult as one can use the public ID. For Schemas things are a bit more tricky though as one only gets the system ID (value of the schemaLocation attribute) in the entity resolver. As this can be anything and is only a hint it doesn't has much use. The other possibility is to use give the parser some XSDs in advance (http://java.sun.com/j2ee/1.4/docs/tu.../JAXPDOM8.html). The downside of this however is that validation is forced to use the Schema even though it normally would use a DTD. A further problem is that J2EE 1.4 uses different XSD files which all share the same namespace and Xerces doesn't like that.

Any ideas on how to do this right?

thanks,
Hendrik
