HTTP Status 403 - Access to the requested resource has been denied
问题原因：
D:\Tomcat5.0\conf 目录下的
tomcat-users.xml 文件内容如下：
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
</tomcat-users>
问题修改：将tomcat-users.xml 文件内容改为
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="admin" password="admin" roles="admin,manager"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
</tomcat-users>
重新启动Tomcat ，在登录时使用 用户名admin 密码 admin 登录即可。
