Class WelcomeFilter

  • All Implemented Interfaces:
    javax.servlet.Filter

    public class WelcomeFilter
    extends java.lang.Object
    implements javax.servlet.Filter
    Welcome Filter This filter can be used to server an index file for a directory when no index file actually exists (thus the web.xml mechanism does not work). This filter will dispatch requests to a directory (URLs ending with /) to the welcome URL determined by the "welcome" init parameter. So if the filter "welcome" init parameter is set to "index.do" then a request to "/some/directory/" will be dispatched to "/some/directory/index.do" and will be handled by any servlets mapped to that URL. Requests to "/some/directory" will be redirected to "/some/directory/".
