You can use RequestBuilder to call the server side logic from your GWT client code. If the server side has a RESTful endpoint it should be relatively easy. If the backend is written using SLSB, I would consider some intermediate layer on the server side (communicating with GWT), because afaik, the session beans are impossible (or close to imposible) to call directly from JavaScript.
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.
