google-code-prettify

I found another syntax highlighting tool. Check google-code-prettify out!.
I followed instructions from one of Philip Johnson's article.

Insert following lines to your <head/> element.



<link href="http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.css" rel="stylesheet" type="text/css"/>

<script src="http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.js" type="text/javascript"/>

Make sure the prettyPrint() function invoked on load of your body tag.



<body onload="prettyPrint()">

Put your source codes between

<pre><code class="prettyprint">

and

</code></pre>

tag like follows.


<pre><code class="prettyprint linenums lang-java">/**
 * A class prints \"hello, world!\".
 *
 * @author Jin Kwon
 */
public class Hello {
    public static void main(String[] args) {
        System.out.println("hello, world!");
    }
}</code></pre>

Note that I had to put the first comment line("/**") to the end of the starting <pre ...>tag for the 'linenums' class works correctly.

And you will get following output.

/**
 * A class prints \"hello, world!\".
 *
 * @author Jin Kwon
 */
public class Hello {
    public static void main(String[] args) {
        System.out.println("hello, world!");
    }
}

I can't say that google-code-prettify is better than Alex Gorbatchev's SyntaxHighlighter.

Check latest dependencies and plugins with Maven

You can check the latest version of each dependency and plugin in your pom. See Versions Maven Plugin.
No additional settings are required. Just run built in goals like this.

Xlet Lifecycle

Xlet's lifecycle can be easily visualized from the four callback methods' definitions.

http://java.sun.com/javame/reference/apis/jsr927/javax/tv/xlet/Xlet.html

LOADED

This state actually is not related with any of four callbacks. This state can be assumed when the default constructor invoked and the Xlet instance has been created.

PAUSED

This state can be reached by one of following paths.

The host middleware invoked initXlet() on the LOADED Xlet instance.
The host middleware invoked pauseXlet() on the ACTIVE Xlet instance.
The Xlet instance (which is ACTIVE) makes itself PAUSED and notifies manager via XletContext.notifyPaused().

ACTIVE

The host middleware invoked startXlet() on the PAUSED Xlet instance.

DESTROYED

This state is the last state every Xlet instances go.

The host middleware invoked destroyXlet() on the Xlet instance.
The Xlet instance (which is not DESTROYED yet) makes itself DESTROYED and notifies manager via XletContext.notifyDestroyed().

One of funky points is that the destroyXlet() method can be invoked from any other states.

Here comes what apidoc saids.

This method may be called from the Loaded, Paused or Active states.

jinahya.googlecode.com

'Jinahya', which is this blog's title, is also refers the project on googlecode.

Project's Address: http://jinahya.googlecode.com

Almost all projects are made with Apache Maven2.

Each project matches following information.

svn repo: http://jinahya.googlecode.com/svn/maven/2/proj/${groupId}/${artifactId}/${version}/
mvn site: http://jinahya.googlecode.com/svn/maven/2/site/${groupId}/${artifactId}/${version}/

And here comes the maven repository you can use.
