a$.$ Make sure your Java EE Netbeans is working properly. b$.$ Work to get the Derby database populated and working with the SDEV$425\_$HW$4$ Web application. c$.$ Study and experiment with the code. For example, even if you haven$$t used CSS style sheets before you should be curious about how color schemes are used and how easily they can be changed in the css file. You should also note how the database connections are made and how JSP and servlets communicate. d$.$ Again, start on this early. This will take you longer than you think.
