Please explain what is the difference between forward() and include() in RequestDispatcher.

They do exactly as their names suggest.
The descriptions in the javadocs are pretty good.

The one key difference between forward() and include() is the fact that forward() clears the output buffer prior to forwarding control to the other servlet (JSPs are servlets ultimately). So, DO NOT forward to another servlet after you've written data to the output stream as the response may already be committed. The include() method merely includes the output of the other servlet inline.
