  1. This enables you to negate a pattern; to say, for instance: 'if the current URL does NOT match this pattern'. This can be used for exceptional cases, where it is easier to match the negative pattern, or as a last default rule. Note: When using the NOT character to negate a pattern, you cannot include grouped wildcard parts in that pattern. This is because, when the pattern does NOT match (i.e.
  2. URL-pattern. If it matches, Tomcat delegates the request to the corresponding webapp. If not, it checks the next pattern in the table, etc.. If the request URI does not match any url-pattern, Tomcat delegates the request to the default webapp. As a corollary to the above : whenever a webapp is stopped (unloaded?) or a new webapp is started (loaded ?), Tomcat for a while stops processing new.

(1) my url-pattern xyz* is not supported by tomcat ( wildcards), (2) this link explains the order of execution of the filters ( filter order ) Based on these discoveries, I changed my requirement: I would be happy to let everyone access /abc/def/xyz/* and block everyone on all other /abc/def/* that dont match /abc/def/xyz* The value of the <url-pattern> sub-element uses a wildcard *, which protects all URLs within the /manager application with this security constraint. The second sub-element defines the role that has access to the protected resource. It does this by using the <role-name> sub-element, which is listed in the following code snippet: <role-name>manager</role-name> The value of this sub-element. The default value is 403.
