Adobe Flex is becoming a popular choice for generating the client side of enterprise
Java applications. Flex applications run on the ubiquitous Adobe Flash Player and are
developed using both ActionScript and MXML. MXML is a declarative, XML-based
language that is preprocessed into ActionScript during compilation. You use it to
create and interact with components such as panels, input fields, and data grids.
ActionScript 3.0 is a powerful, object-oriented programming language that is used for
the core logic of Flex applications. Flex development has a fairly low learning curve
due to the striking similarity between Java and ActionScript in language features,
concepts, and syntax. The languages use similar conditional statements, looping
syntax, and even coding conventions (Figure 4-9).
The UI portion of Flex applications are typically constructed using MXML. This
is a declarative, XML-based language that is pre-processed into ActionScript during
compilation. You use MXML to create and interact with components such as panels,
