If I am not wrong, you need something called XmlJavaTypeAdapter. I used this a long time ago and I do not have my code handy right now, but please take a look at the link and if you are still stuck then do give me a shout.
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.
