Re: DOCBOOK-APPS: Error with Xalan-J 2.4.0 and DocBook XSL 1.58.1

[Patrick Hartling <patrick at vrac dot iastate dot edu>]

Hmm, it appears that my problem is related to the JDK version rather than 
to the stylesheets or the XSLT processor.  I was using 1.4.1_01, but if I 
use 1.3.1_06 instead, I get no errors (with the 1.58.1 stylesheets and 
Xalan-J 2.4.1).

To answer your question, I did not see the aforementioned error with the 
1.57.0 stylesheets.  It's easier for me to change my $JAVA_HOME 
environment variable than it is to change XSLT processors, so I think 
I'll go with JDK 1.3.1.
