You should have a web.xml file in your WEB-INF directory. If you are unaware of how this works then you really need to learn JSP thoroughly. Consider buying a book or similiar.

But to eliminate other problems, simply call the full name of the servlet instead.

If the servlet doesn't have a package, then you can call it from the root of your development structure (your jsp files should be in the view directory, so the directory above that).

eg:
http://localhost:8080/emploginServlet

Obviously if the classes are in a package, then call the class using it's full package name eg:
http://localhost:8080/com.example.pa...mploginServlet
