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
