[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - error with hibbernate - entity class not found

[vlad2005]

Work to an project based on adobe flex on client side, and java with hibernate at server side.
Anyway, am not an expert on java or jboss.
So i have installed on my windows desktop, eclipse with java 1.6, and jboss 4.2.3 GA. In my project i have hibernate with class mapping to table into an database. Everything work well.
Now i want to move my application to my server that is freebsd 7.0
So i installed jboss 4.2.2 GA and java 1.5 (that is in ports collection).
Jboss start without any problem, so next i move my application into deploy directory. When i start jboss, i receive these errors:

There, "spa.Service.vo.Marcatb", is my custom class.
My classes are simple, with variable declaration, setter and getter methods. I have tables created into mysql database. 
Where is the problem?
