This will prevent the small possibility that any of the applications
don??™t work for some reason.
In terms of IDE, you can use whatever you like. My own personal preference is for nothing
but a good text editor (I recommend UltraEdit for Windows, www.ultraedit.com) and a command
line. Choice of an IDE is a highly personal matter; some people such as me prefer no
IDE at all, others swear by Eclipse or NetBeans or IDEA or some other product. I??™m not here to
try and sway your opinion in any direction, but for the sake of consistency, everything in this
book will assume no IDE at all and will assume everything is done from a command prompt. I
will also be assuming a Windows environment, although there??™s no reason you can??™t do everything
in a *nix environment.
USE THE SOURCE, LUKE!
At this point I??™d like to point out that all of the source code for this book, including ready-to-run WAR files for
all the projects, can be downloaded from the Apress web site at www.apress.com. Once there, click the
Source Code/Download link and find this book in the list, which will bring you to the download page.
Please note that this is not just a suggestion, it is all but required to move forward! From this point out, I
will assume that you have downloaded the source code, have unzipped it, and therefore have it available to
refer to.
