RE: deployment of web app

I have the correct file structure from what I can tell...It must be something in one of my .xml files, I just do not know how to handle them

deployment of web app

I am attempting to deploy my first web application. I have read many tutorials and have worked on it for sometime now. I simply cannot understand what is needed to complete the process. I do not know what files need to be modified and placed where. This is what I have come up with so far.
