I have this in my console when I insert in database, I use MySQL 5.0 and hibernate2 :

Hibernate: insert into employe 
(prenom, mail, adresse, tel, service, fonction, login, password
 , matricule, nom, id) 
  values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

net.sf.hibernate.transaction.JDBCTransaction cannot be cast to net.sf.hibernate.odmg.Transaction

any solution please

I TRIED DIFFERENT TYPE OF TRANSACTION BUT DIDNT WORK :(

You have imported the wrong Transaction class. Check your import statements.

By the way, seriously consider upgrading to hibernate 3.x

I guess you create your transaction the wrong way. Use:

Transaction myTransaction = mySession.beginTransaction();

... where mySession is your session object you have already created.
