Hi all,

I've put hibernate2.jar in $JBOSS_HOME/server/default/lib, but when I try to use hibernate, the following error occurs:

java.lang.NoClassDefFoundError: net/sf/hibernate/collection/Set
 at net.sf.hibernate.type.TypeFactory.set(TypeFactory.java:200)
 at net.sf.hibernate.mapping.Set.getCollectionType(Set.java:29)

 at net.sf.hibernate.cfg.Configuration.add(Configuration.java:249)
 at net.sf.hibernate.cfg.Configuration.addInputStream(Configuration.java:
285)

No matter what I do, I get this error. I checked and there is no another hibernate2.jar file deployed, no class duplicated, the net/sf/hibernate/collection/Set class is in the hibernate2.jar.
Probably it's a jboss class loader problem. Someone has already had this problem? Did someone fix this problem?

Thanks,
