Giving multiple URL patterns to Servlet Filter
servlet-filters, servlets, url-pattern
Solution
If an URL pattern starts with `/`, then it's relative to the context root. The `/Admin/*` URL pattern would only match pages on `http://localhost:8080/EMS2/Admin/*` (assuming that `/EMS2` is the context path), but you have them actually on `http://localhost:8080/EMS2/faces/Html/Admin/*`, so your URL pattern never matches.
You need to prefix your URL patterns with `/faces/Html` as well like so:
<url-pattern>/faces/Html/Admin/*</url-pattern>
You can alternatively also just reconfigure your web project structure/configuration so that you can get rid of the `/faces/Html` path in the URLs so that you can just open the page by for example `http://localhost:8080/EMS2/Admin/Upload.xhtml`.
Your filter mapping syntax is all fine. However, a simpler way to specify multiple URL patterns is to just use only one `<filter-mapping>` with multiple `<url-pattern>` entries:
<filter-mapping>
<filter-name>LoginFilter</filter-name>
<url-pattern>/faces/Html/Employee/*</url-pattern>
<url-pattern>/faces/Html/Admin/*</url-pattern>
<url-pattern>/faces/Html/Supervisor/*</url-pattern>
</filter-mapping>
Problem
I am using a Servlet Filter in my JSF application. I have three groups of Web pages in my application, and I want to check Authentication for these pages in my Servlet Filter: my Folders ``` /Admin/ *.xhtml /Supervisor/*.xhtml /Employee/*.xhtml ``` and I am writing `web.xml` like ``` <filter> <filter-name>LoginFilter</filter-name> <filter-class>com.ems.admin.servlet.LoginFilter</filter-class> </filter> <filter-mapping> <filter-name>LoginFilter</filter-name> <url-pattern>/Employee/*</url-pattern> </filter-mapping> <filter-mapping> <filter-name>LoginFilter</filter-name> <url-pattern>/Admin/*</url-pattern> </filter-mapping> <filter-mapping> <filter-name>LoginFilter</filter-name> <url-pattern>/Supervisor/*</url-pattern> </filter-mapping> ``` but requests like ``` http://localhost:8080/EMS2/faces/Html/Admin/Upload.xhtml ``` are not entering into Filter. I have to provide security to these 3 folders. How to solve this problem ?
