what could be the problem?
Also I am using Head first JSP and servlets book and when i try to access the form.html in the Beer-v1\form.html i get a http 404 error, but when i use it under the directory jsp-examples it works. I have created the WEB-INF directory also.
Would be a great help if anyone can solve the problem .
