摘要: 求助：一个jsp连接sqlserver数据库的问题
检验数据库是否连接成功的原程序如下：
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<head>
</head>
<body>
<%
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=xionglu";
String user="sa";
String password="sql";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement();
String sql="insert into dd values('4','xxx','44')";
stmt.executeUpdate(sql);
%>
</body>
出现的错误页面如下：
type Exception report

description The server encountered an internal error () that prevented it from fulfilling this request.

望高手门指点指点，谢谢大家～！
你有没有把下面三个包导入工程？
检查数据库
msbase.jar
mssqlserver.jar
msutil.jar
是不是端口被占用了，或者数据库路径问题无法连接到数据库
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
没有newInstance()
详细看一下：
http://tech.163.com/05/0830/15/1SDQL2CI00091589.html
数据库没启？数据库没打补丁？
Class.forName是静态方法
.newInstance()应该是不用的
javax.servlet.ServletException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
从这里看好像是在创建连接的时候出了问题
我以前也碰到过这类问题，原因可能没有打补丁，或者3个包没有放置。
3个包都放进去了，环境变量也设了，这个程序在别人机器上运行都能连接上，而且和我用的是一样的sql server 2000+SQLServer 2000 Driver for JDBC
javax.servlet.ServletException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
从这句我也感觉是驱动器的问题，但是我重新下载过别的驱动器也还是不行
楼上的兄弟说的补丁是什么？是sql server 2000的补丁吗，我看别人也没打过补丁啊
sp3
谢谢各位，我已经装了sp4补丁了，问题已经解决，再一次表示感谢
