The Java Scripting API, introduced in Java SE 6, provides support that allows Java
applications and scripting languages to interact through a standard interface. This API is
detailed in the JSR 223, “Scripting for the Java Platform” and is contained in the
Several scripting languages have script engine implementations available that conform to JSR 223. See the “Scripting Languages” section in Chapter 17 for a subset of these supported languages.
ScriptEngine provides the fundamental
methods for the API. The class
works in conjunction with this interface and provides a means to establish the desired
scripting engines to be utilized.
The scripting API includes the ability to embed scripts and/or scripting components into Java applications.
The following example shows two ways to embed scripting components into a Java
application: (1) the scripting engine’s
reads in the scripting language syntax directly, and (2) the scripting engine’s
eval method reads the syntax in from a file.
