Hibernate代码现场服务器无法正常工作，但在localhost

我在Hibernate.My代码面临的问题的工作是本地服务器上的工作，但不要对正在server.I正在使用Hibernate代码现场服务器无法正常工作，但在localhost

public void saveEmployee(Emp employee) { 
    Session session = HibernateUtil.getSessionFactory().openSession(); 
    Transaction transaction = session.beginTransaction(); 
    session.save(employee); 
    transaction.commit(); 
    session.close(); 
}

的数据保存。和HibernateUtil类：

import org.hibernate.cfg.AnnotationConfiguration; 
import org.hibernate.SessionFactory; 

/** 
* Hibernate Utility class with a convenient method to get Session Factory 
* object. 
* 
* @author Jitendra 
*/ 
public class HibernateUtil { 

    private static final SessionFactory sessionFactory; 

    static { 
    try { 
     // Create the SessionFactory from standard (hibernate.cfg.xml) 
     // config file. 
     sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory(); 
    } catch (Throwable ex) { 
     // Log the exception. 
     System.err.println("Initial SessionFactory creation failed." + ex); 
     throw new ExceptionInInitializerError(ex); 
    } 
} 

    public static SessionFactory getSessionFactory() { 
    return sessionFactory; 
    }

}

使用此代码。

和错误的堆栈跟踪是
