Who know the reason, please tell me.

Answer 1

put <security-constraint> tag also in your web.xml defining the <web-resource-collection>, <web-resource-name>, <url-pattern> and the
<role-name>manager</role-name> inside <auth-constraint>, This role-name is important and you have to add this role in your tomcat-users.xml also. See sample web.xml in ..\webapps\manager\WEB-INF
Dont know if this is the reason why ur problem is coming though,
