Hi, You might want to revisit a few key elements of the Deployment Descriptor as explained in the Servlet Specification. These include: - The use of welcome-file to serve the resource /. You typically do NOT want to define a servlet at url-pattern /. - url-pattern does not include the docBase, but rather it's relative to the docBase. So for http://yourhost/yourwebsite/Login, the url-pattern is just /Login.
Read the Servlet Specification, it answers your questions completely and in detail. That's what it's for.
