Hi,
I'm using the xerces parser inside xalan or saxon.
I want to use xml catalogs, to access DTD offline with their URL.
It seems, that xerces is issueing an internet connection, even if all files
are available locally.
I use:
- jdk-1.4.1
- xerces-2.3.0
- saxon-6.5.2 or xalan-2.5.d1
- resolver-1.0 (apache) or resolver-1.1 (sun)
Stack traces without an internet connection show:

I belief this error to be on the xerces side, because xalan and saxon show the
same
behaviour and error messages.
Can somebody help me with this issue, or is this really a bug ?
