Using the test program included below I get a ClassCastException at line 1176
of the
DeferredDocumentImpl class. This looks like it should work to me, but I haven't
dug
into it very deeply. I am using JDK1.2.2 with the latest CVS download of Xerces
(at least
as of 4:00 PM CST 12/30/1999.) I will debug as much as I can over the weekend,
but
if someone has already solved this I would appreciate an email.
The test files are included below. You will probably have to fix up the
pathname to the
XML file in the Java class' init() method and the pathname of the DTD in the
XML file.
This worked until I added a call to configDoc.getIdentifier(String) in the
processChild()
method.
