Scenario Webstart Extension

Scenario version 0.5 is out. For the list of features and enhancements check out Hans's announcement here.

One of the things we have done for this and will do for future releases is to provide a webstart extension for Scenario binaries. Using the extension allows for simpler deployment for webstart enabled applications which use Scenario. Instead of hosting Scenario binaries on your website you can reference them using extension tag in resources section of you jnlp file. The extension for release 0.5 is available here: http://download.java.net/javadesktop/scenario/releases/0.5/Scenario-0.5.jnlp.

Take this demo for example: (Note: java 6 is required to run it)
