Hi Kevin, One solution to your problem is to register your own entity resolver [1] on the parser. Given the URI of the schema passed to the entity resolver, you can retrieve it from another source, such as from within a jar. You can then return an InputSource containing the InputStream or Reader you've opened (or another URI for the parser to read from).
If your document references are relative URIs you need to set the system ID on the InputSource otherwise Xerces will resolve them relative to the directory where Java was launched. Certainly not the behaviour most users expect but with an InputStream alone there is no context for resolving relative URI references. You must provide this base URI if parsing your document requires resolving external entities. Hope that helps.
