How to include output of resources like (JSP,ASP,CGI,PHP,HTML) located on different physical machines into a main JSP output?

The only way to do that is using java.net.URLConnection. There are a lot of FAQ and Forum answers on how to use it, so if you need help on it, take a look at them.

Why <jsp:forward.../> works only for relative url? Probably because that tag is passing the request and response objects and not generating a new connection. The information that are inside the objects are strictly related to the context so you cannot send them throught the wire to another machine.
