Tools Required

I've made some assumptions while writing the application programming examples in this book. During the writing of this book, I used a Windows 2000 server and two Windows XP workstations (along with other devices). I also tested many of the examples using Windows 9 x . The test machines included SQL Server and MySQL. I also created Web server setups using Internet Information Server (IIS) and Apache. The test base was as broad as I could make it, but it wasn't possible for me to test every combination of machine and software.

I tested all of the examples in this book using the most current version of the appropriate language product. In most cases, I tell you which language version I used as part of the example description. I don't guarantee that the example will work with any older versions of the product, nor did I test using educational versions of products. Given the relative simplicity of Google Web Services, however, I'm certain that most examples will work with any newer version of the supported language.

All of the desktop and Web application examples will work on a single machine, but I tested all database applications on a two-machine setup as well to ensure you could place the database on another machine. The mobile device applications are all tested using an actual device, but I also tested them using an emulator. Chapter 9 tells you how to work with emulators and presents a number of emulators you might try when writing your application.
