Professor Sun, I'm confused. What's the difference between these two and when should they be applied? Request vs. getServlet

I assume you mean request scope vs application scope, i.e. whether to use request.setAttribute() or getServletContext().setAttribute().

The answer is basically the same as the answer to the Scope question you asked before - it depends on how you want to use the data and how long you want to keep the data.

 

Ok. Thanks Professor.

From the Edit Comment. I get it now. Thank you.
