尝试保存在MySQL数据库中时发生异常

我想创建一个Web服务以在MySQL中保存帐户：

package didList;

import javax.jws.WebService;

@WebService
public class Accounts {

public Integer addAccount(String fullName, String username, String password, Boolean isAdmin , Boolean isShowInList){
    Taccount person = new Taccount (fullName,username,password,isAdmin , isShowInList);
    System.out.println("test1");
    AccountManager SVTDB = new AccountManager();
    System.out.println("test2");
    return SVTDB.addAccount(person);
  }
}

它在此行之前打印“ test1”：

AccountManager SVTDB = new AccountManager();

但它不打印“ test2”，所以该行有问题，

package didList;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

public class AccountManager {
    private static SessionFactory factory;

    public AccountManager() {
        try {
            NewHibernateUtil.initConnection();
            factory = NewHibernateUtil.getSessionFactory();
        } catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);

        }
}

public Integer addAccount(Taccount acc) {
    Session session = factory.openSession();
    Transaction tx = null;
    Integer accID = null;
    try {
        tx = session.beginTransaction();
        accID = (Integer) session.save(acc);
        tx.commit();
    } catch (HibernateException e) {
        if (tx != null) {
            tx.rollback();
        }
    } finally {
        session.close();
    }
    return accID;
 }
}

这是NewHibernateUtil类：

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class NewHibernateUtil {

private static SessionFactory sessionFactory;

public static void initConnection() {
    try {
        sessionFactory = createSessionFactory();
    } catch (Throwable ex) {
        // Log the exception. 
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }

}

private static SessionFactory createSessionFactory() {
    Configuration config = new Configuration();
    config.configure("hibernate.cfg.xml");
    return config.buildSessionFactory();
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
}

这是我看到的异常：

将hibernate jar文件添加到项目的类路径中。

If you are using eclipse or netbeans simply add the jar file from 
hibernate/lib/required folder into build path of the IDE.
If you are not using any IDE any go to advance system setting and set 
classpath of all jar files.

不要忘记将休眠库也放在lib文件夹中。
