I suspect you are getting complaints about unhandled exception type IOException. If that's the case, you need to put the call to mgr. Open in a try-catch block to handle the exception that may occur when retrieving the InputStream object.
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.
