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

Full stack trace of any exception that occurs: net.sf.ehcache.CacheException: Error configuring from jar:file:/C:/Daten/Eclipse%20Workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/webapps/SMV%20Online/WEB-INF/lib/ehcache-1.2.jar!/ehcache-failsafe.xml. Initial cause was Error configuring from input stream. Initial cause was null:12: Could not set attribute "path".. Message was: java.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)

I've solved the problem by switching to another Eclipse workspace directory. Dunno what the error was caused by in the first place, but now my application is up an running, again.
