[EJB 3.0] - Persistence in EJB3
by masoodah＠mdsit.com
Hi,
I am new to EJB3. I am using Persistence to connect to Mysql
I got the following error when I try to deploy
11:32:39,410 INFO [EJBContainer] STARTED EJB: com.dreamplay.dpds.ejb.LogonTopicBean ejbName: LogonTopicBean
11:32:39,894 INFO [EJB3Deployer] Deployed: file:/C:/jboss-4.2.0.GA/server/default/deploy/DPDS-Server.jar

My persistence.xml looks like this

-------------------------------------------
And my method call is
EntityManagerFactory entityMangerFactory = Persistence.createEntityManagerFactory("DPDS"); EntityManager entityManager =
entityMangerFactory.createEntityManager(); EntityTransaction entityTransaction = null;
try{
entityTransaction = entityManager.getTransaction();
entityTransaction.begin();
UserDAO userDao = new UserDAO();
userDao.setUserId(userObj.getUserId());
userDao.setPassword(userObj.getPassword());
userDao.setLogonTime(userObj.getLogonTime());
entityManager.persist(userDao);
entityTransaction.commit();
} catch( Exception exc ){
if ( entityTransaction != null ){
entityTransaction.rollback();
}
} finally {
entityManager.close();
entityMangerFactory.close();
}
Please help me. What I am doing wrong.
Thanks
