Yes I tried. I'm using tomcat 4.1.12. Actually if I replace the xercesImpl.jar
but the latest version in the common/endorsed directory that work fine (this is
normal). So I suppose that is not possible to use two differents version of
xerces, one used by the server and the other one used by a webapp. I'm wrong?
Actually, this is really weird since in the log file, tomcat load the good
xerces jar:
....
2002-11-25 10:45:12 WebappLoader[/axis]: Deploy JAR /WEB-INF/lib/xercesImpl.jar
to C:\java\jakarta-tomcat-4.1.12\webapps\axis\WEB-INF\lib\xercesImpl.jar
....
It must not override the classes already loaded from the endorsed dir.

Have you try with the SUN JDK 1.3.1? Which version of Tomcat are you using?

Hi,
I created a very small servlet and when I try to run it I got a VerifyError
exception (see below). The servlet try to create a instance of JAXP
DocumentBuilder. I use xerces 2.2.1, that work with previous versions. That work
also on the client side (xerces 2.2.1 and without tomcat). The JDK used is IBM
jdk1.3.1. Any ideas of what wrong? Thanks
