sun.org.mozilla.javascript.internal.NativeObject

all data exchange between the Java code and the executed script should be done through primitive variables, strings, and Java objects (for example, beans) whose properties and methods can be accessed very easily in the JavaScript code. Simply said, don't try to access native JavaScript objects in your Java code. Use Java objects in the JavaScript code instead.

Note that javax.script.Invocable is an optional interface, which some script engines may not implement. The JavaScript engine that comes with JDK 6 does support this interface.

you can significantly reduce the execution time by compiling the scripts, using the methods provided by another optional interface named javax.script.Compilable, which is supported by the JavaScript engine of JDK 6.
