Hi,
it looks to me to be a problem/mismatch in the choice of XML Parser. I
have experienced similar Problems when having several/alternative
parsers in the "endorsed" Directory of the JDK.

So my belief is there is an XML Parser in the CLASSPATH or
SYSTEMCLASSPATH which overwrites the one coming along with the JDK.

(JDK1.4: crimson)
(JDK1.5: xerces)

Regards
Michele
