Generally, a servlet sends an HTML page to a browser. Anything you can do in an
HTML page, you can do with servlets. The servlet gives you the capability to
dynamically create the HTML page. Have the servlet place the tags for whatever
control you want into the page that it sends back to the browser. Building a
control is outside of the scope or charter for this list. Check the MS site for
ActiveX.

The generic servlet is intended to provide any kind of server side processing.
This means it runs inside a server. You would invoke the servlet using whatever
socket and protocol the server accepts for client-server interaction.
In the case of HttpServlets, which are designed specifically to interact with
HTTP requests from browsers, the easiest way is to use a form or link from an
HTML page. However, there is nothing special about this. If you know how to
connect to a web server, you could bypass the browser, open a socket connection
directly to port 80, and send all the information needed by the servlet by
following the HTTP protocol.

Sure. See above for the answer to #1 and #2.
