I couldn't find anything on ServletPortlet mapping thing. So I used Resource mapping for sending a pdf with Spring Portlet MVC using annotations. Ref: http://developers.sun.com/portalserver/reference/techart/jsr286/jsr286_2.html.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
