JSP代码片断:

//调用存储过程查询，需要返回查询结果

 public ResultSet callQuery (String proc)

  }
  catch (SQLException ex)
  {
   System.err.println("DAO.DBBean.executeQuery() ERR :"+ex.getMessage());
  }
  return rs;
 }
 
 //调用存储过程更新，不需要返回
 public void callUpdate (String proc)
 {
  rs=null;
  stmt=null;
  try{
   System.out.println("{CALL "+proc+"}");

   cStmt.execute();
  }
  catch (SQLException ex)
  {
   System.err.println("DAO.DBBean.callUpdate() ERR :"+ex.getMessage());
  }
 }

 

//插入数据。添加用户，在注册时使用
 public void addUser(UserBean user) throws SQLException {
