Flex Java
If you'd asked me a few years ago if I'd ever write a book, I would have laughed at the
thought. All through high school and college I loathed writing anything more than a
short answer, and when it came to writing papers, I was usually one of the people ask-
ing about the minimum length required for a passing grade. Now here we are, thou-
sands of words and hundreds of pages later, and BJ and I have survived writing our
first book, twice.
So how did I go from absolutely loathing writing to being willing to dedicate so
many nights and weekends to writing this book? Since the first 1.0 release of the Flex
framework, I've been a fan. I discovered Flex while I was distaining HTML/JavaScript
and browser compatibility issues. I was trying to prototype a form-heavy application
with complex business rules and validation, struggling with goofy layout issues and
JavaScript errors, and was looking for a better solution. Although it's possible to make
rich web applications using HTML and JavaScript, it's easy to make ugly ones. Most of
the nice AJAX frameworks we take for granted today didn't exist at the time, and many
developers had absolutely no idea what AJAX was.
One night, while searching for an alternative, I ran across this excellent framework
that allowed you to write Flash-based applications using a declarative syntax and a pro-
totyping scripting language similar to JavaScript, without the cross browser issues
because it all ran in the Flash Player. So I picked up a copy of Developing Rich Clients
with Macromedia Flex by Steven Webster and Alistair McLeod and immediately fell in
love with the Flex framework. There was only one problem: it was expensive. It was
going to be a hard sell for any but the largest projects.
