<%@ page import="java.sql.*"%>
<%@ page import="java.util.*"%>
<%@ page import="java.io.*"%>
<%@ page import="com.microsoft.jdbc.sqlserver.SQLServerDriver"%>
<%@ page import="java.lang.*"%>
<%@ page contentType="text/html; charset=gb2312"%>
<%
request.setCharacterEncoding("gb2312");
String CLASSFORNAME="com.microsoft.jdbc.sqlserver.SQLServerDriver";
String SERVANDDB="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=school";
String USER="sa";
String PWD="sa";
%>
chaxun.jsp文件代码如下:
<%@ include file="mybag.inc"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
</head>
<body>
<%
//获得请求的参数。
String id=request.getParameter("tuser");
String psw=request.getParameter("pwd");
//连接数据库
Class.forName(CLASSFORNAME);
Connection con = DriverManager.getConnection(SERVANDDB,USER,PWD);
Statement statement=con.createStatement();
String isCorrect="select * from users where userid='" + id + "' and password='" + psw + "'";
ResultSet result=statement.executeQuery(isCorrect);
out.print(result.getString("username"));
%>
</body>
</html>
运行chaxun.jsp文件后出现以下错误,小弟没有办法解决,请教各位大哥
