Extend your Java Application with Embedded Languages

A scripting engine, built in the language of your choice, and embedded into your application can make a huge difference to your customers, who have concerns about extensibility. Even better, creating a scripting engine is easy and fun. See three versions of a spam filter engine built in Groovy, Jython, and BeanShell.

hat happens when a potential customer goes through the feature list for your application and finds just one or two missing items? Do you have a mechanism for them to extend your application to handle those features? Or will you lose the sale to an application that can be extended? Embedded scripting languages can turn a static vertical application into a dynamic application platform that will adapt rapidly to changing customer requirements.

And lucky for you Java is an extremely popular platform for embedded scripting languages. Why? Because the garbage collection and reflection capabilities of the Java language and framework make it easy to build parsers, compilers, and interpreters that work on any platform and can make use of the Java framework.
