我先前安装了tomcat5.5的编译运行都好,可是连接数据库(ms sql server2000)连接驱动::(jdbc-odbc sp1))(jdk1.5)的时候,可就是无法运行,不知道错在哪里??????请高手赐教,编译运行的时候,有以下提示::;

我是按照以下网上搜集的安装方法配置的,不知道错在哪里请高手指点!!!!
JSP连接SQL Server 2000系统配置2004-08-18 18:10 作者： MYLiao 出处： Java研究组织 责任编辑：方舟 第三步：----安装JSP访问SQL Server 2000的驱动程序:
从微软的网站上下载驱动程序：SQL Server 2000 For JDBC 驱动程序，在Google中随便搜索就有。
然后将它安装好。(比如安装目录是D:\SQLDriverForJDBC。)
然后必须将安装目录中的lib目录下三个jar文件：
msbase.jar,mssqlserver.jar,msutil.jar拷贝到Tomcat目录下common\lib目录下，之后，修改环境变量中的CLASSPATH，
把SQL Server 2000 For JDBC 驱动程序安装目录下的
D:\SQLDriverForJDBC\lib\msbase.jar;D:\SQLDriverForJDBC\lib\mssqlserver.jar;D:\SQLDriverForJDBC\msutil.jar;追加到CLASSPATH中去，修改后的CLASSPATH如下：
CLASSPATH=D:\Java\bin;.;D:\Java\lib;D:\Java\lib\dt.jar;
_D:\Java\lib\tools.jar;D:\LubeeTomcat\common\lib\servlet.jar;
_D:\SQLDriverForJDBC\lib\msbase.jar;D:\SQLDriverForJDBC\lib\mssqlserver.jar;D:\SQLDriverForJDBC\msutil.jar
必须重新启动Tomcat！
这样做的目的是，jsp页面在编译过程中不会出现找不到sql server driver类库的问题
写一个简单的用来测试连接SQL Server 2000的JSP代码
＜%@ page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html;charset=gb2312" %＞
＜html＞
＜body＞
＜% Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs";
//pubs 为你的数据库的
String user="sa";
String password="admin";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select job_id,job_desc from jobs";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) { %＞
您的第一个字段内容为：＜%=rs.getString(1)%＞＜br＞
您的第二个字段内容为：＜%=rs.getString(2)%＞＜br＞
＜% } %＞
＜% out.print("数据库操作成功，恭喜你"); %＞
＜% rs.close();
stmt.close();
conn.close();
%＞
＜/body＞
＜/html＞ 
请告知!!!!!!!
