[jboss-user] [JBoss jBPM] - ERROR: ... CGLIB Enhancement failed ...
Hi, i'm just starting up with jbpm and trying to get it to work with my Oracle 10g DB.
I've written a small test case just creating the schema, and deploying a simple
process but I get "CGLIB Enhancement failed" errors on alot (maybe all)
hinernate-mapped classes, see the log below.

| | If you use lazy loading with proxies (default for all classes in Hibernate 3),
Hibernate needs to subclass your class at runtime. It can't do this if you have a
private no-argument constructor. As per documentation, at least package visibility is
required.

|
| I've checked the jbpm code and there are ofcource no "private no-argument
constructors", they are all public... so i'm wondering what's going on here?
Anoyone has any idea? I have probably missed something but i'm kind of stuck so
i'd appreciate all help.
