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!!!!!!!
----------------解决方案--------------------------------------------------------
你试试为你的SQL SERVER打上SP4,应该可以解决此类问题.
----------------解决方案--------------------------------------------------------
如果用Jdbc直连的话,是需要打sp3或是sp4的补丁,你可以先试试桥接的方法行不行.
----------------解决方案--------------------------------------------------------
楼上的我打上了sql server2000 sp3的补丁,还是不行,请问还有什么办法???编译java程序没有问题,编写jsp没有问题,就是连接数据库有问题???请解决11!
----------------解决方案--------------------------------------------------------
你先试下在JAVA程序中能否正常连上。JAVA连SQLSERVER本来就不是很好。要打很多补丁
----------------解决方案--------------------------------------------------------
数据源建了吗?
----------------解决方案--------------------------------------------------------
access试试.
----------------解决方案--------------------------------------------------------
有谁能告诉我怎么办呀/?//难道就没有高手能连接sql server2000数据库吗??????请把具体步骤写明,请赐教!!!
----------------解决方案--------------------------------------------------------
以前弄过,好像要在控制面板中设置一下数据源的,具体怎么做忘记了??
----------------解决方案--------------------------------------------------------
真是奇怪,论坛主题就是jsp怎么连接数据库这么初级入门的问题都解决不了???我是菜鸟,你们也是菜鸟吗???
