[jboss-user] [JBoss jBPM] - ERROR: ... CGLIB Enhancement failed ...

[anre42]

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.
