ResourceHandler stop hosting files with jetty 9 - 404 not found error (works fine with jetty 8)

Question

Apparently, ResourceHandler stop hosting files with jetty 9 - 404 not found error (works fine with jetty 8). Here is the code:

    ResourceHandler resourceHandler = new ResourceHandler();
    resourceHandler.setDirectoriesListed(true);
    resourceHandler.setResourceBase("some_resource_base");

    HandlerList handlerList = new HandlerList();
    handlerList.setHandlers(new Handler[]{servletHandler, resourceHandler});
    server.setHandler(handlerList);
    server.start();

This quistion with the accepted answer does not seem to work against jetty 9 - Serving static files w/ embedded Jetty

Answer 1

Assuming that servletHandler is a ServletContextHandler

(Note: it best not be an actual ServletHandler , as that's an internal class, not meant to be instantiated directly)

Then the resourceHandler will never be called, as the DefaultServlet processing (or Default404Servlet ) at the end of the ServletContextHandler chain will always respond, not allowing resourceHandler to even execute.

If you have a ServletContextHandler , do not use ResourceHandler use the DefaultServlet in that ServletContextHandler to setup and serve your static files.

Answer 2

In case somebody is looking for a working example, this is how I combined a ResourceHandler with a ContextHandler (partially based on current Jetty docs: Jetty documentation )

        srv = new Server();
        ServerConnector srvConn = new ServerConnector(srv);
        srvConn.setHost("localhost");
        srvConn.setPort(8080);
        srvConn.setIdleTimeout(30000);
        srv.addConnector(srvConn);
        //used for webSocket comm later:
        ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
        context.setContextPath("/");

        //for static  content:
        ResourceHandler resH = new ResourceHandler();
        resH.setDirectoriesListed(true);
        resH.setWelcomeFiles(new String[]{ "index.html" });
        resH.setResourceBase("./my/web/root");
        ContextHandler resCtx = new ContextHandler();
        resCtx.setHandler(resH);

        //Add both ContextHandlers to server:
        ContextHandlerCollection handlers = new ContextHandlerCollection(resCtx, context);
        srv.setHandler(handlers);
