SSH 集成的系统中 事务不能成功开启： Transaction not successfully started

Question

因为我是通过某个字段删除相关记录，由于该字段不是主键之类的
所有通过hibernate 的session 调用hql 来删除记录。
代码如下：

  /**
     * 删除操作
     */
    public void deleteRP(String hql){
        Session session=this.getSession();
        Transaction t=session.beginTransaction();
        session.createQuery(hql).executeUpdate();
        t.commit();
        session.flush();
        session.clear();
    }

执行完上面代码后，数据成功删除，但是页面显示 500 错误，提示如下

org.apache.struts.action.RequestProcessor.processException(516) | Unhandled Exception thrown: class org.springframework.transaction.TransactionSystemException
2009-8-20 17:33:03 org.apache.catalina.core.StandardWrapperValve invoke

很郁闷的问题，总是提示事务不能成功开启, 各位帮忙分析下 是什么原因？

你是用spring管理了事务吧，
修改下

/**
 * 删除操作
 */
public void deleteRP(String hql){
    Session session=this.getSession();

    session.createQuery(hql).executeUpdate();

    session.flush();
    session.clear();
}
