Every time i write the code i get the HTTP STATUS 404 requested resource is not available.
please do give some suggestions.

Follow the usual debugging steps:

Be sure that your servlet is in a package other than the default.

Make sure that your servlet is properly mapped to a URL in the deployment descriptor.

Make sure that you use the mapped URL properly when addressing the servlet. Don't forget to include the context path.
