运行后在java的dos框里看不到出错信息（它是显示了，但是我无法移动左右键去看。）
我的数据源名为my_test,程序如下：
<%@ page language="java"%>
<%@ page info="database handler"%>
<%@ page import="java.io.*"%>
<%@ page import="java.util.*"%>
<%@ page import="java.sql.*"%>
<%@ page import="javax.servlet.*"%>
<%@ page import="javax.servlet.http.*"%>
<%
Class.forName("sun.jdbc.odbc.jdbcOdbcDriver");
String url="jdbc:odbc:my_test";
Connection con=DriverManager.getConnection(url,"sa","");
Statement statement=con.createStatement();
String query="select * from classmate";
ResultSet result=statement.executeQuery(query);
