jsp jdbc 的问题弄一天了 快疯了 求救

Ide ：myeclipse  tomcat 5.0    sql 2000 sp4打好了  xp系统
环境变量里的驱动路径设置   d:\jdbc\msbase.jar;d:\jdbc\msutil.jar;d:\jdbc\mssqlserver.jar;  
代码如下：
<%@ page contentType="text/html;charset=gb2312"%> 
<%@ page import="java.sql.*"%> 
<html> 
<body> 
<%
String url="jdbc:microsoft:sqlserver://localhost:1433;databasename=销售数据库"; 
String user="sa"; 
String password=""; 
try{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
Connection con = DriverManager.getConnection( url, user, password );
Statement stmt = con.createStatement(); 
String sql="select * from article"; 
ResultSet rs = stmt.executeQuery( sql );
while(rs.next()) {
%> 
您的第一个字段内容为：<%=rs.getString(1)%> 
您的第二个字段内容为：<%=rs.getString(2)%> 6
<%
}
%> 
<%out.print("数据库操作成功，恭喜你");%> 
<%
rs.close(); 
stmt.close(); 
con.close(); 
}catch(Exception e){
e.printStackTrace(System.out);
}
%> </body>
