Hello,
on creating the session factory (using caveat emptor HibernateUtil) in our JSF (myFaces) project, we get a ClassNotFoundException referring to a class containig the composit id of a trinary relation. Couriously, this error only occors when we create the session factory in our jsf project.
For debugging reasons, we have created the session factory with the same configuration files and pojos using a static void main class - and there, the session factory is started without any problem and returns every result perfectly. But every time we create a SessionFactory inn a managed bean, the ClassNotFoundException is thrown. (When we delete the hbm [and the associations to the associated classes] of the class the ClassNotFoundException refers to the exception is not thrown any more.)
We have been searching for the reason for this courious behaviour the whole day with four persons, but we have no idea how to solve the problem. Has anybody of you had a similar problem or at least an idea where to search for the reason?
Here still some information:
- the class NutzerrechtPK is the class containig the trinary ID
- NutzerrechtPK implements the interface serializable and the methods equals(NutzerrechtPK) and hashCode()
- we use tomcat 5.0
- we use hibernate 3.0
- we use jsf implemented by myFaces
Although, this is not very beautiful, I post the stack trace at the end of this message.
