Hi Tushar,
It isn't obvious to me what's going wrong here. Have you tried Xerces
1.4.3? When the parser requests the original schema document--the one
doing the importing--do you provide it with an InputSource? Is the
systemId or publicId on the InputSource set? If not, you could try doing
that and seeing if this helps; I have a feeling it might.
Cheers,
Neil

Subject: RE: Problem using EntityResolver
I checked It does not return NULL.
I open the source code put the debug statements in openImportedSchema
method and
it tries to see a circular dependency of the import schema and itself. But
itself is null i.e.(fCurrentSchemaURL)
Has any one been successfule to use Entity Resolver with schemas and import
clause in schema?
Tushar.
private Element openImportedSchema(String location) throws Exception {
// expand it before passing it to the parser
InputSource source = null;
System.out.println("Location "+ location + "Current Schema "
+fCurrentSchemaURL);
if (fEntityResolver != null) {
source = fEntityResolver.resolveEntity("", location);
}
if (source == null) {
location = expandSystemId(location, fCurrentSchemaURL);
source = new InputSource(location);
}
else {
// create a string for uniqueness of this imported schema in
fImportLocations
if (source.getPublicId () != null)
location = source.getPublicId ();
location += (',' + source.getSystemId ());
}
if (fImportLocations.contains((Object)location)) {
System.out.println("fImportLocations.contains((Object)location");
return null;
}
// check to make sure we're not importing ourselves...
if(source.getSystemId().equals(fCurrentSchemaURL)) {
// REVISIT: localize
System.out.println("// REVISIT:localize");
return null;
}

In your entity resolver class are you sure that you are not returning
a NULL?
Either by falling through to the default behaviour of the else block.
Or that your catch statement is catching a FileNotFoundException.

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
