I am having problems with the WebappClassLoader. I am getting a ClassNotFoundException when it try load a class from spring.jar inside my application. But this problem don't happen when I use JBoss-3.2.5...only with JBoss-4.0.0. Have something changed ?

The ear structure:

My ear:
spring.jar
myapp.war

My war:
...
META-INF/MANIFEST-MF

My MANIFEST-MF:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.5.3
Created-By: 1.4.2-b28 (Sun Microsystems Inc.)
Class-Path: spring.jar
Built-By: rmoura
...

Thanks
