From "Charles Webber" <charle...@earthlink.net>
Subject Re: newbe: class directory question
Date Mon, 10 Sep 2001 21:29:02 GMT
Oh, and one other piece of information.  If I change the URL manually, so
that I say http://localhost/book/servlet/coreservlets.ShowParameters, the
servlet appears to display stuff properly, even though it doesn't have
values from the html form passed through.
What I am hoping to get is the answer on where I should place my servlets,
and how to configure Tomcat so that I can simply use
http://localhost/book/coreservlets.ShowParameters and get the same output.
Hope this helps.
