Re: Barracuda and Jivan

Hmm...  Arno, I'm not sure that what you are saying here is true.  I've 
just tested this under Tomcat-5.0.16 and I replaced the existing 
xercesImpl.jar and xmlParserAPIs.jar with those from Xerces-2.6.0.  These 
are in the common/endorsed directory.  I ran Tomcat and loaded up a 
document in Jivan in almost exactly the same way Jancsi is doing it and it 
worked just fine.  No errors.  The document loaded perfectly.  Not sure how 
you are seeing something different???
