Which version are you using? That should work...let me check.

Sorry for the delay.

I'm using grizzly-servlet-webserver-1.9.18a.jar downloaded today.

Thanks. Nick.

Hi Nick,

the example you provided doesn't work because of specifics how HTTP Mapper searches for appropriate ServletAdapter to process a request. Basically it never reaches "find Adapter by extension" point, because "find Adapter by prefix", which is executed before, always finds a match.

If you'll change the code to this [1], it will work, and hope, work as you expected :)

WBR,

Alexey.

[1] 

        int port = 7070;

        GrizzlyWebServer ws = new GrizzlyWebServer(port);

        ServletAdapter mysa2 = new ServletAdapter();

        MyServlet myServlet2 = new MyServlet();

        myServlet2.setMessage("Hello, I am Two!");

        mysa2.setServletInstance(myServlet2);

        mysa2.setProperty(ServletAdapter.LOAD_ON_STARTUP, 1);

        mysa2.setContextPath("/");

        mysa2.setServletPath("/*.two");

        ws.addGrizzlyAdapter(mysa2, new String[]{"/*.two"});

        ServletAdapter mysa1 = new ServletAdapter();

        MyServlet myServlet1 = new MyServlet();

        myServlet1.setMessage("Hello, I am One!");

        mysa1.setServletInstance(myServlet1);

        mysa1.setProperty(ServletAdapter.LOAD_ON_STARTUP, 1);

        mysa1.setContextPath("/");

        mysa1.setServletPath("/");

        ws.addGrizzlyAdapter(mysa1, new String[]{"/"});

        ws.start();
