Debug level Hibernate log excerpt:

I signed all libraries for jnlp delivery but still it doesn't help. I am sure, the "Job" class does not occure in any jars.

UPDATE: Fixed problem myself by extracting all jars and set classpath to them. So there appear to be conflicting jars. (I use some additional frameworks like swixml, jfeechart...)[/code]
