This concise introduction shows you how to build applications with Roo, using the frameworks shell as an intelligent and timesaving code-completion tool. Its an ideal RAD tool because Roo does much of the tedious code maintenance. Youll get started by building a simple customer relationship management application, complete with step-by-step instructions and code examples.
