Title: Hello World (using Beanshell)
Description: This is a Chameleon Beanshell version of the original Xholon "Hello World" tutorial.
Url: http://www.primordion.com/Xholon/doc/tutorial.html
InternalName: HelloWorld
YoutubeId:
Keywords: Hello World, Xholon, tutorial, Beanshell
My Notes
--------
In this version of the Xholon "Hello World" tutorial:
The infrastructure is provided by Xholon Chameleon.
The Hello and World script objects are interpreted using Beanshell.
The code is written as Java.
**To run this app, select the basic Chameleon launcher.**
OR (under development)
----
This app can be run in the Bestiary, although it's more complex because the Bestiary:
- is a Java applet, and is therefore subject to a stronger security policy which forbids use of a Java bytecode compiler
- does not use the default Xholon GUI
Follow these steps:
- Load the Xholon Bestiary page at::
http://www.primordion.com/Xholon/pulpcore/Bestiary/index.html
- Press "Start app"
- Navigate to a Cat node by pasting the following into the console textarea, and then pressing the Submit button::
xpath ../descendant-or-self::*[@name='cat_2']
- Paste the contents of "Step 4" below, into the console, and press Submit.
- Navigate to the HelloWorldSystem node by pasting the following into the console textarea, and then pressing the Submit button::
xpath *[4]/*
- Paste the contents of the Hello script into the console, and press Submit.
- Paste the contents of the World script into the console, and press Submit.
- Watch the Java Console for "Hello World!".
