ResultSet is closed!!!为什么？
<%@ page contentType= "text/html; charset=GBK " %>
<html>
<head>
<title> connect the db </title>
</head>
<%@ page import= "java.sql.* "%>
<body bgcolor= "#ffffff ">
<%
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver ");
String url= "jdbc:odbc:JSPuser "; // message_DSN 为你的用户数据源名称；
String user= " ";
String password= " "; // 用户名和密码在此都设为空；
String name;
String pwd;
String c;
name=request.getParameter( "name ");
pwd=request.getParameter( "pwd ");
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement();
String sql= "select * from TBuser where name= ' "+name+ " '; ";
String pd= "select * from TBuser where password= ' "+pwd+ " '; ";
ResultSet rs1=stmt.executeQuery(pd);
ResultSet rs=stmt.executeQuery(sql);
%>
<%
if ((rs1.getString(2)).equals(rs.getString(2)))
out.println( "OK ");
else
out.println( "Error ");
%>
<%rs.close();
rs1.close();
stmt.close();
conn.close();
%>
</body>
</html>
以上是JSP代码。。。
问题是出现了
