Try to use the complete STS Version 2.9.x instead offen a self assembled eclipse. Because It looks like you eclipse is missing AspectJ. If you use the complere STS (Not only the sping plugin) then there ins everything you need.
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.
