Problem using EntityResolver

[tu...@employease.com]

Xerces 1.4.2:
When I try to parse a document with xml files and schema files in the same
directory. The parsing works fine.
But Instead if Iset my own EntityResolver in the parser it fails.
I have included SourceCode for Parser, Resolver.
If you need I can provide you with the XML and xsd files.
Also the Stack Trace is 

java.lang.NullPointerException
