    Default Re: 404 Status Error

    preeti91...if you don't have a default page and don't specify MyServlet in the URL then you will get a 404.

    Did you try .../f/MyServlet ?

    First, to start from your login.html page, either you need to map it on your deployment descriptor(web.xml), then do HOST_NAMEORT and after that, in your login.html, put in the form tag, the action attribute which would actually request container for your servlet. If you still facing the problem, let us know.
