(急)jsp文件连接sqlserver数据库的问题
我用如下的jsp文件连接sqlserver数据库,
<%@ page contentType= "text/html;charset=gb2312 "%>
<%@ page import= "java.sql.* "%>
<html>
<body>
<%
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db_board ";
//pubs为你的数据库的
String user= "sa ";
String password= " ";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select * from tb_User ";
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)%>
<%}%>
<%out.print( "数据库操作成功，恭喜你 ");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
不知为什么出现如下的错误,是不是我的sqlserver数据库有问题啊?已打了sp4补丁,tomcat\lib下也有jdbc驱动,用的是1433端口,
在dos下:
ping (服务器IP地址ip)
连接正常...
或
ping (服务器名)
连接正常...
telnet ＜服务器IP地址＞ 1433
正在连接到localhost...不能打开到主机的连接， 在端口 1433: 连接失败
请问大家一下这可能是什么问题啊!
下面是jsp读取sqlserver数据库出现的错误:

[解决办法]
到了三个驱动包了没有啊msbase.jar、mssqlserver.jar、msutil.jar
[解决办法]
打sql2000的sp4补丁
在dos 下输入netstatu -an 看sql2000端口 打开没有
[解决办法]
sqlserver的端口和防火墙端口冲突的，关了防火墙试验下。。。
[解决办法]
是否与防火墙有关。
[解决办法]
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket
1433没有打开
