I found what was wrong, the begin() was not at the right place :
query = ...
homeobj = (Home) query.getSingleResult();
_ut.begin();
homeobj.setTitle("new-title");
_ut.commit();
Sorry for the trouble. I'll write a little sample to clarify all that
(for me at least)
The @TransactionAttribute still does the error "cannot read:
mp/adminservlet.java"
this is the function :
@TransactionAttribute
public boolean set_homeinfo(int id_user,String title)
