Just to narrow this question. I have created my servlet filter and have updated the web.xml file in the portal-server.war directory. The filter entry | <filter> | <filter-name>mobileFilter</filter-name> | <filter-class>com.axegroup.jboss.servlet.filters.MobileDeviceFilter</filter-class> | </filter> | <filter-mapping> | <filter-name>mobileFilter</filter-name> | <url-pattern>/*</url-pattern> | </filter-mapping> | This works, in that it calls my class before processing the portal request. However, I want to apply this to context /portal and all children of this. When I enter the | <filter-mapping> | <filter-name>mobileFilter</filter-name> | <url-pattern>/portal</url-pattern> | </filter-mapping> | context in the mapping my class is no longer executed. Any ideas here? Cheers, Troy View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4177915#...
