Xalan not thread-safe?
Hi,
I've been using Xalan/Xerces for years without any noticeable problem,
but I now have to face a possible thread-safe problem.
I have a web site runned by Tomcat4, and I use the JSTL XSLT Transformation
tag.
When I stress the web site, I get a strange exception from times to times
from Xalan/Xerces.
Once this exception is thrown, I have to restart the JVM, because no other
XSLT transformation can be processed.
Can you help?
Thanks.
xalan 2.4.1 and xerces 2.3.0
