Why go through all that hassle? Simply place the JSP somewhere in a folder structure under WEB-INF and there will be no way for it to be accessed directly via URL.

22. Servlet Forward Command

The Java object model, I guess. If you really don't trust another servlet in the same application, then you should do a browser-redirect instead of a forward. It's a bit slower an clumsier, but that way there is a completely different request with completely different parameters. But may I ask why you think this might be a problem? The "destination" servlet ...

34. Doubt in forwarding to Servlet/JSP in another Application

That's correct but keep in mind that with an include(), you're sending the original request object (via server side call)but with a redirect you're sending a new request (by sending the location to the browser and asking it to ask for that resource).

49. mod_rewrite vs Servlet forwarding

I don't think there is a single answer to that. But I would say that URL rewriting is for modifying URLs (possibly in a user-visible way, and possibly for a high-level selection of resources) whereas servlet forwarding is a way for a Java server app to delegate responsibility. Ideally, these actions are distinct enough that it should guide your implementation. Maybe ...
