还是没明白啊
可不可以说清楚一下啊
谢谢了～～

是不是这些啊？
我有写啊
<parameter>
     <name>username</name>
     <value>sa</value>
    </parameter>
    <parameter>
     <name>password</name>
     <value></value>
    </parameter>　　　　
是不是很笨啊～　
麻烦你了真的不好意思

我哥哥给我做了一个网络办公系统,用JSP技术做的,在他那里用都好好的,可我拿回来就出现这个问题,数据库我重装的,所有准备工作都做好了,结果就出现这个问题了.
好郁闷啊,自己弄不明白,干着急,请再帮帮我吧

系统变量新建了
SQL Server的驱动程序放在Tomcat\common\lib里了
Tomcat\conf\server.xml的文件也配置了
启动Tomcat\bin\startup.bat也成功了
登录界面出来了，输入用户名和密码就不行

怎么测试啊？
我只会ODBC的测试
不会JDBC的测试
再麻烦你教教我

其实你这样说是很伤我自尊的
不过没关系了
谁叫我这么笨的呢
我没学过JSP
只是课堂上学过java语言，都是基础的东西
不好意思，让你见笑了

版主说的对
谢谢版主
