There are two issues with your post:

1. No description of the error or the issue is provided, just code.
2. This is the ObjectDB forum. Please use the Hibernate forum for Hibernate specific questions.

 Sry.

the error is that i get in return a endless array with message in users and users in message So my annotations are not right.

Another forum? They all to seem to be dead or am i wrong?

Thx

This is still not the best description of an error (obviously if you get error messages you should include them in your question). Anyway, for Hibernate questions you may try Stack Overflow.
