I understand that sir but unfortunately am using the servlet runner as a server for my servlet programs..!!

The same idea still applies. I've never used ServletRunner, but I'm going to guess that it won't like your paths either. 403 errors can be caused by many things, one of which is that the filesystem prevents the server from accessing a directory, in this case maybe the
examples directory.

I will guess that your URL:

should instead be something like
