MDN’s new design is in Beta! A sneak peek:

Rhino Examples

Examples have been provided that show how to control the JavaScript engine and how  to implement scriptable host objects. All the examples are in the git tree at mozilla/js/rhino/examples.

Sample Scripts

The unique.js script allows printing unique lines from a file.

The liveConnect.js script shows a sample usage of LiveConnect (Java-to-JavaScript connectivity).

The jsdoc.js script is a JavaScript analog to Java's javadoc. It makes heavy use of regular expressions.

The checkParam.js script is a useful tool to check that @param tags in Java documentation comments match the parameters in the corresponding Java method.

The enum.js script is a good example of using a JavaAdapter to implement a Java interface using a JavaScript object.

The NervousText.js script is a JavaScript implementation of the famous NervousText applet using JavaScript compiled to Java classes using jsc. It can be run in the HTML page NervousText.html.

Controlling the JavaScript Engine

The RunScript class is a simple program that executes a script from the command line.

The Control class is a program that executes a simple script and then manipulates the result.

JavaScript Shell is a program that executes JavaScript programs; it is a simplified version of the shell in the tools package. The programs may be specified as files on the command line or by typing interactively while the shell is running.

PrimitiveWrapFactory is an example of a WrapFactory that can be used to control the wrapping behavior of the Rhino engine on calls to Java methods.

Multithreaded Script Execution is a program that creates a single global scope object and then shares it across multiple threads. Sharing the global scope allows both information to be shared across threads, and amortizes the cost of Context.initStandardObjects by only performing that expensive operation once.

Implementing Host Objects

First check out the tutorial if you haven't already.

The Foo class - Extending ScriptableObject is a simple JavaScript host object that includes a property with an associated action and a variable argument method.

The Matrix class - Implementing Scriptable provides a simple multidimensional array by implementing the Scriptable interface.

The File class - An advanced example extends ScriptableObject to provide a means of reading and writing files from JavaScript. A more involved example of host object definition.
