-
-<pre>
-	require( "org.luaj.lib.j2se.Luajava" )
-</pre>
-
-<p>

-See the following example for more details:
-<pre>
-	src/sample/LuajavaRunner.java
-</pre>
-
-<p>
-Because reflection is required by the implementation, this is only usable from the J2SE platform.
-
-<p>
-You must include the library <b>lib/luaj-j2se-${VER}.jar</b> in your class path.
-

-You can try sample code that creates a simple Swing UI using:
-<pre>
-	java -cp luaj-j2se-${VERS}.jar lua src/test/res/swingapp.lua

+See the sample midlet int <em>src/sample/SampleMIDlet</em> for an example.

+	require 'org.luaj.lib.DebugLib'

+The <em>lua</em> command line utility includes the debug library by default.

+<h3>The Luajava Library</h3>
+The J2SE platform includes the <em>luajava</em> library, which simplifies binding to Java classes and methods.  
+It is patterned after the original <a href="http://www.keplerproject.org/luajava/">luajava project</a>.
+
+<p>
+The following lua script will open a swiing frame on J2SE:

+
+<p>
+The J2ME platform does not include this library, and it cannot be made to work because of the lack of a reflection API in J2SE.
