Tips for Scripting Java with Jython

BANGALORE, INDIA: Maybe you're writing a Java program, and you need to do a quick one-off script to clean up your database. Sure, you could write it in Java, but that can involve a lot of overhead for a quick script. You could write it in an outside scripting language, but you'd really like access to the business logic already in your Java program.

Or maybe you’re writing a servlet, and the requirements are changing quickly. Your data model is changing, and you're having trouble keeping all the type information consistent.

Or maybe you’re writing a standalone program, and you'd like to use the large variety of tools already written for Java, but you'd also like to use a tool that makes your program 25-50 percent shorter, and easier to write and maintain.

Jython is the tool for you.

Jython is a complete re-implementation of the Python programming language, written in 100 percent pure Java, which runs on any Java Virtual Machine (JVM). Python is a high-level, interpreted, object-oriented scripting language which combines elegant syntax rules with powerful built-in objects to create a language that is very easy to write, read, and maintain. Python is perhaps most notorious for its use of indentation to mark the beginning and end of statement blocks.
