This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Though 'all can be done' I have the following remark, question with respect to the formulation of Assignment Servlet 4b. The graphics say: -1- videologin.htm for login (thats ok) So we do. -2- VideoLogin (servlet) says: you are loggen in (ok). Two buttons: Add a new video, list the videos (ok). So we push:Add a video -3- AddVideoServlet (servlet) shows the inputfields for a video with a submit button (ok) AND two buttons for add a video and list a video. Is 'add a video' at this place really what I want? What is the difference between submit and add a video??? It means I would like to 'not see' the 'add a video' button. We press submit -4- AddVideoServlet(servlet) with message: Video added and two buttons. (ok) But does this mean that the 'AddVideoServlet' should rememember how it is called? Push list video button. -5- ListVideoButton (servlet) shows available videos (ok) But again with two buttons: add a video and list a video. I would delete: list a video. Don't I see the list?
You make excellent points! My position on this is that I want to keep the assignments simple. By always having the same stuff at the bottom, I'm making less to code up, less for folks to understand and write, and most importantly, less to nitpick.
