Hello, I'm trying to build an authentication mechanism using the <security-constraint> tag in web.xml
E.G. <security-constraint> <web-resource-collection> <web-resource-name>My App</web-resource-name> <url-pattern>*.action</url-pattern> <url-pattern>*.jsp</url-pattern> </web-resource-collection> <auth-constraint> <role-name>aliveadmin</role-name> </auth-constraint> </security-constraint> This snippet says that any url ending with ".action" or ".jsp" should be authenticated first, and works OK. However, I need to exclude some specific urls which end with ".action". (e.g. RSS feed urls that contain the string "rss"). Is there a way to do so with the example I brought above? (I tried to define this rule by a regexp, but tomcat showed errors on startup about that.) Thank you, any links related to this are as well welcome. Kind regards, Nareg Garabedian
