Introduction
What is Beanshell?
BeanShell is a lightweight, embeddable Java interpreter that lets you execute standard Java code dynamically at runtime. It supports full Java syntax along with scripting conveniences like optional typing, method closures, and simplified commands.
Because it's lightweight and written entirely in Java, BeanShell can be easily embedded in Java applications to provide scripting and runtime extensibility.
You can call it from your code to evaluate expressions, run methods, or customize behavior on the fly. Alternatively, it can be used as a standalone script engine to interact with Java objects and APIs dynamically.
Since it runs in the same JVM as your application, you can pass live objects into BeanShell scripts and receive modified results—enabling powerful integration for configuration, automation, rapid prototyping, testing, and interactive debugging.
In essence, BeanShell brings dynamic Java execution and flexible scripting into a single, embeddable tool for enhancing and extending Java applications.
