JSP连接SQL的问题,虽然是老生常谈,但是以前的相关解决方法都试了,还是没成功,不知如何是好!
程序:test.jsp
<%@ page contentType= "text/html;charset=gb2312 "%>
<%@ page import= "java.sql.* "%>
<%@ page import= "com.microsoft.jdbc.sqlserver.SQLServerDriver " %>
<html>
<body>
<%Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
String url= "jdbc:microsoft:sqlserver://localhost:1305;DatabaseName=test ";
//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 test ";
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>
浏览后的出错提示:

我已把C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib目录下的三个jar文件拷到了D:\Tomcat 6.0\lib目录下,真不知是哪里出了问题,向各位请教了!
[解决办法]
又不是包找不到....关键是这个
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
tomcat 6以上的好象要用JDK1.6版本的.把tomcat换为5.X.X的吧
[解决办法]
不好意思,Tomcat 6.0 可以用 JRE 5.0的.
http://apache.mirrors.tds.net/tomcat/tomcat-6/v6.0.10/README.html
1.数据库url对吗
2.数据库打开了吗?
３．帐号密码对吗？
4。是SQLServer 2000吧？
[解决办法]
Error establishing socket错误
首先你先检查你数据库是否使用 你的1305端口（默认是1433的） 防火墙是否屏蔽1305端口
如果都没有问题 进CMD 使用NETSTAT -AN检查1305端口是否开启 没有的话需要打MS SQL SERVER的SP3 OR SP4 补丁。。。。。。。。。。
