tomcat - Default servlet getRequestDispatcher of a static page -

@webservlet("/") public class rootservlet extends httpservlet {     private static final long serialversionuid = 1l;      protected void processrequest(httpservletrequest request, httpservletresponse response)             throws servletexception, ioexception {         string pathinfo = request.getservletpath();         switch(pathinfo) {                 case "/":                     this.handlehomepage(request, response);                     break;                 default:                     request.getrequestdispatcher(pathinfo).forward(request, response);             }     } 

i'm trying use default servlet catch context root url. when it's root url, handled handlehomepage method. if not, forwarded corresponding file. e.g. css, html, images file. cause never-ending exception occur. getrequestdispatcher allow forwarding static page?

you better create filter :

@webfilter(filtername = "rootfilter", urlpatterns = { "/*" }, dispatchertypes = { dispatchertype.request }) {     @override     public void dofilter(servletrequest p_orequest, servletresponse p_oresponse, filterchain p_ochain) throws ioexception, servletexception     {         // skip non-http requests         if(!(p_orequest instanceof httpservletrequest))         {              p_ochain.dofilter(p_orequest,p_oresponse);         }         else         {             string pathinfo = ((httpservletrequest)p_orequest).getservletpath();             switch(pathinfo)             {                 case "/":                     // forward "root servlet"                     break;                 default:                     p_ochain.dofilter(p_orequest,p_oresponse);             }         }     } }
