Hi everybody. I'm trying to make jpa2web ( http://jpa2web.sourceforge.net/ ) work with tomcat 7.04 but I'm having some issues.
I have followed the tutorial here ( http://www.ibm.com/developerworks/web/library/wa-aj-jpa2web/ ) step by step and i ended up having a war folder in my c:\tomcat\webapps folder.

However, when I try to access it, i get an 404 error : The requested resource () is not available.

I tried to start it using Tomcat manager but after i pressed start it gave me the following error:

FAIL - Application at context path /msmihai.war could not be started

In the tomcat error log i found this:

INFO: Deploying web application directory msmihai.war
Nov 21, 2010 12:21:54 AM org.apache.catalina.core.StandardContext startInternal
SEVERE: Error listenerStart

I have no idea what is wrong with this, as I configured everything EXACTLY as the tutorial said.

My msmihai.war folder has a lot of zul files in it ( probably because jpa2web uses ZK).

The web.xml file :


<?xml version="1.0" encoding="UTF-8"?>
