JRuby Developers Join Sun
The two core JRuby developers, Charles Oliver Nutter and Thomas Enebo, will soon join Sun to work on JRuby full-time. As Nutter says in his blog, JRuby Developers Join Sun, "the primary goal is to give JRuby the attention it really needs. The potential for Ruby on the JVM has not escaped notice at Sun, and so we'll be focusing on making JRuby as complete, performant, and solid as possible." David Herron also comments on the move in his blog Good news, JRuby developers coming to Sun.
Applet(s) of the Day from JGame
The JavaDesktop Community's latest featured applet is actually 3 applet games that have been created with the new JGame framework for 2D games. According to the release 0.8 announcement: "JGame is a small high-level 2D game engine for producing games on a variety of platforms. It does a lot of the stuff you need for a game automatically, and classic type arcade games can be developed with a minimum of effort. It is based on sprites with automatic collision detection, and a tile-based background with easy sprite-tile interaction facilities. JGame games can easily be run as stand-alone applications or as applets, and can be scaled to any resolution."
30 minutes Flex test-drive for Java developers
The 30 Minute Flex Test Drive gives Java developers a way to explore Flex and the various ways it integrates with Java EE, with a minimal time commitment: you just deploy a war file in Tomcat (or another app server), and then go through 10 concise and targeted samples. The samples focus on integrating Flex with Java back-ends (remote method and web services invocation, server push, real-time collaboration, pub/sub messaging, JMS integration, and persistence).

Compatibility Assertion Tagging Within Specifications
One of the most time consuming aspects of creating Technology Compatibility Kits (TCKs) for the various JSRs which come out of the Java Community Process is the creation and maintenance of assertion lists. This entry explores the idea of tagging assertions within a written Java specification.

Dynamic role handling
For web based authentication to work, all the roles must be known at runtime to setup the deployment descriptor. The problem is that my application needs to manage roles at runtime. So far that is no problem because I'm able to create them using the JdbcRealm and EJBs. But I need to update the deployment descriptor evertime a new role is is inserted because the login mechanism won't accept the new roles until I update the security section in the deployment descriptor, so that this role can access the different areas in my web application. Is there a way around this, possibly without having to implement a custum security realm? —
Re: I think, there could be existing a unique Java-license
So for PNG we have what I would regard as a healthy situation - run-of-the-mill apps just use the RI as-is, and some specialised software re-implements a part of it. For the latter, it's valuable that they can refer to the RI without having nightmares about becoming "tainted". This actually encourages compatibility, because it allows the specialised implementations to be derived from the RI.For TCP/IP you have a similar situation - just about every OS has code derived from the BSD implementation, but with their own tweaks. That hasn't led to TCP/IP chaos, rather the opposite. —
