I only use any one of the following when i run the program, when i use new.jsp, i get a page, but when i use index.html i get an error 404, both are in the same directory, (i.e) under WebContent/.

I have entered both here for ur understanding

hey guys, When the welcome file is a jsp then it loads the page, If i change it to a html, it hits me with a 404 error. I have checked with other codes. everything seems to be correct. I cant quite get what i have done wrong here.
