I've used both Jacob and Com4j in while integration against a simple COM object. I ended up going with Com4j mainly because Jacob leaked too much memory. Compared to Jacob, I think that Com4j was more straight forward once it is set up.
If I remember correctly, Jacob required much more setting up and typing before doing the actual COM call. While in Com4j you'll just use the provided factory.
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.
