Scripted Objects 

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell is a natural scripting language for Java. This requires the library bsh-2.0b4.jar to be in classpath. The following example shows creating a scripted object in beanshell script.

File Name  :   /BEAN_SHELL001/config/scripted_objects.bsh

mathlib() {   //Property   PI = 3.14;   //Method   sum(a, b) {     return a + b;   }      return this; } lib = mathlib(); print("PI value : " + lib.PI);  print("Sum : " + lib.sum(2, 4));
