Grizzly Embedded Server + Jersey service + Servlet filter

Question

The following code runs my REST service but my servlet filter never gets called. Any ideas?

WebappContext webappContext = new WebappContext("grizzly web context", "");

FilterRegistration testFilterReg = webappContext.addFilter("TestFilter", TestFilter.class);
testFilterReg.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), "/*");

ResourceConfig rc = new ResourceConfig().register(MyResource.class);
HttpServer httpServer = GrizzlyHttpServerFactory.createHttpServer(URI.create("http://localhost:8080/myapp/"), rc);
webappContext.deploy(httpServer);

Answer 1

In short, registering your ResourceConfig in the manner as you have done above will effectively bypass the Grizzly Servlet container.

In order to leverage the Servlet Filter, you will need to something like this:

    WebappContext webappContext = new WebappContext("grizzly web context", "");

    FilterRegistration testFilterReg = webappContext.addFilter("TestFilter", TestFilter.class);
    testFilterReg.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), "/*");

    ServletRegistration servletRegistration = webappContext.addServlet("Jersey", org.glassfish.jersey.servlet.ServletContainer.class);
    servletRegistration.addMapping("/myapp/*");
    servletRegistration.setInitParameter("jersey.config.server.provider.packages", "com.example");


    HttpServer server = HttpServer.createSimpleServer();
    webappContext.deploy(server);
    server.start();
