I have a big problem with my current webapp project. I keep on getting the following exception. The exception occurs when my HibernateUtil class (as per the bible) first tries to create the SessionFactory and therefore tries to configure EhCache. I have not changed anything about the jar files or the code in the HibernateUtil class and I am close to desparation, so I really hope that there are some users around here who know this problem and can tell me about a solution. Thanks a lot in advance

Hibernate version: 3.2

Development Tools: Eclipse Webtools 1.0

Runtime Environment: Apache Tomcat 5.5.9
