数据库数据输出为空白
代码是这样的：
<%@ page contentType= "text/html; charset=gb2312 " language= "java " import= "java.sql.* " errorPage= " " %>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> 无标题文档 </title>
</head>
<body>
<%
final String DBDRIVER = "com.microsoft.jdbc.sqlserver.SQLServerDriver " ;
final String DBURL = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=myjob ";
response.setCharacterEncoding( "GBK ");
Connection conn = null ;
ResultSet rs = null ;
String name=null;
String password=null;
String user= "sa ";
String pass= " ";
//String name1=new String(request.getParameter( "name ").getBytes( "ISO8859_1 ")).trim();
Statement st=null;
PreparedStatement stat=null;
boolean flag=true;
Class.forName(DBDRIVER) ;
conn = DriverManager.getConnection(DBURL,user,pass) ;
st=conn.createStatement();
rs = st.executeQuery( "select email from user1 where name= '11 ' " ) ;
rs.close();
conn.close();
%>

问题是：
访问此页面的时候输出为空白，网页的框架也不见了，哪位高手帮忙看看，先谢过了。
[解决办法]
你的rs是不是应该拿到最下面页面输出后再关阿

[解决办法]
晕 你RS关的太早了结果集都清空了
[解决办法]
rs关早了
另外你在rs = st.executeQuery( "select email from user1 where name= '11 ' " ) ; 后面加个输出看看 如果out.println能输出 那估计就是字符格式的问题
[解决办法]
缺少rs.next();
导致rs.getString()异常
