The old notion of platform has been replaced with creation of globals. The old notion of platform has been replaced with creation of globals.
Two classes are provided to encapsulate common combinations of libraries. The <a href="http://luaj.sourceforge.net/api/3.0/org/luaj/vm2/Globals.html">Globals</a>
class holds global state needed for executing closures as well as providing
convenience functions for compiling and loading scripts.
<h2>Platform</h2>
To simplify construction of Globals, and encapsulate differences needed to support
the diverse family of Java runtimes, luaj uses a Platform notion.
Typically, a platform is used to construct a Globals, which is then provided as a global
environment for client scripts.

<h3>JmePlatform</h3> <h4>Android</h4>
This class can be used to set up the basic environment for a Java ME application. Android applications should use the JsePlatform, and can include the <a href="#luajava">Luajava</a> library
to simplify access to underlying Android APIs.
A specialized Globals.finder should be provided to find scripts and data for loading.
See <a href="examples/android/src/android/LuajView">examples/android/src/android/LuajView</a>
for an example that loads from the "res" Android project directory.
The ant build script is <a href="examples/android/build.xml">examples/android/build.xml</a>.
<h4>Applet</h4>
Applets in browsers should use the JsePlatform. The permissions model in applets is
highly restrictive, so a specialization of the <a href="#luajava">Luajava</a> library must be used that
uses default class loading. This is illustrated in the sample Applet

<h4>MIDlet</h4>
MIDlets require the JmePlatform.
The JME platform has several limitations which carry over to luaj.
In particular Globals.finder is overridden to load as resources, so scripts should be
colocated with class files in the MIDlet jar file. <a href="#luajava">Luajava</a> cannot be used.
