Using XSDBuilder to build XML Schema objects

Question

I want to parse an XML document using an XML Schema Definition that I provide explicitly to the parser, rather than one identified in the document being validated. It appears that I can create an XML Schema object using XSDBuilder, and give it to the XML parser using XMLParser.setXMLSchema(). The problem is that XSDBuilder.build() wants an XSD system ID that is a file, and I want to retrieve XSD documents from non-file-based stores. Ideally, I'd like to give the builder a stream containing the XSD, or barring that, provide a custom entity resolver that it can use. Any ideas how to go about doing that? Or am I going about this the wrong way?
Thanks for any advice,

Hi,
I didn't test it wit XML Schema, but any parser that finds a system ID should call an implementation of EntityResolver that returns an InputSource for the system ID.
An InputSource is a wrapper around an InputStream and its url and it ssystemID.
An example for sun's parser is on http://www.s-line.de/homepages/gerd_castan/java/resolve.html
(I "tested" this code also with oracles DTD and Schema parser. This means that I used this code for oracle, too, but I didn't go through the debugger to see what it does.)
Cheers,
