无法进入 TOMCAT 管理后台

[ebridge2001]

修改了配置文件：
<tomcat-users>
<!--
NOTE: By default, no user is included in the "manager-gui" role required
to operate the "/manager/html" web application. If you wish to use this app,
you must define such a user - the username and password are arbitrary.
-->
<!--
NOTE: The sample user and role entries below are wrapped in a comment
and thus are ignored when reading this file. Do not forget to remove
<!.. ..> that surrounds them.
-->
<!--
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="tomcat,manager-gui"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
-->
</tomcat-users>

但是还是无法通过使用配置的用户名和密码访问后台，我到底哪里错了？求指教，谢谢

我知道错了。 抱歉，如此大意。 没有去掉注释。
