Hi,
I am new to EJB3. I am using Persistence to connect to Mysql
I got the following error when I try to deploy

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
