Thanks for the instance comment that helped.
Here's where I'm at now. I am successfully calling the AddVideoServlet and adding the video. I get a true on add and have a count increase when I add. So far so good.
The ListVideoServlet however knows nothing about what was added. If I check to see what was added by AddVideoServlet, I get back a big fat 0 for the number of videos, which was my concern. ListVideoServlet has no knowledge of where the videos were added. How should it know where to look for what has been added into memory? My thoughts are that these objects need to be aware of each other but I'm not sure how to make that happen when they don't talk to each other.
