If you set up a brand new tomcat with the default configuration, you are unable to access the manager servlet. All requests on http://[YourHost]:[TomcatPort]/manager/html are responded by a HTTP Status 403 ("Access to the requested resource has been denied"). If you use your tomcat for a productive system the manager servlet should always be deactivated. The tomcat's default configuration hides the manager servlet for some security reasons. If you want to access the manager servlet you should add some lines to your tomcat-users.xml at $CATALINA_HOME/conf/tomcat-users.xml and restart your tomcat.

The default content of tomcat-users.xml is:

<?xml version='1.0' encoding='utf-8'>
<tomcat-users>
    <role rolename="tomcat" />
    <role rolename="role1" />
    <role rolename="admin" />
    <user username="tomcat" password="tomcat" roles="tomcat" />
    <user username="role1" password="tomcat" roles="role1" />
    <user username="both" password="tomcat" roles="tomcat,role1" />
</tomcat-users>
