Sun launch ‘Java-Powered’ logo promotion

Sun have started a ‘Java-powered’ logo advertising promotion that was launched this month at JavaOne.

The promotion aims to include a Java logo on devices that include a Java JVM inside, which already includes millions of cell phones shipped world-wide. Sun has the opportunity to cash in on the success of J2ME shipped with mobile phones if they can pitch this right – Java is already out there in the consumer market, the tough part now is increasing consumer awareness to cash in on the popularity.

Resolving Classloader issues

O’Reilly have a good article on their OnJava.com site on resolving classloader issues – they cover both the more simple ClassNotFoundException, as well as the more confusing NoClassDefFoundError.

I don’t think I had come across NoClassDefFoundError in 8 years of working with Java, until the last year where I have been developing with IBM’s Websphere Studio Application Developer. It works with your projects as WAR, JAR and EAR files expanded to your filesystem anduns them like this within it’s Websphere test server environment. If you don’t have the correct JAR dependencies set between projects then you are guaranteed to see some NoClassDefFoundErrors…

Java Timeline at JavaOne

Had I been there this year this is something that I would have liked to have seen… a huge timeline whiteboard set out over several boards on a wall, where people could add their own experiences with Java.

There are some pretty good resolution pictures on the java.net site here.

Bruce Tate on the next programming paradigm shift

Bruce Tate has some interesting comments on the announcements at JavaOne this week, on how developers have ‘hit the wall’ with the current programming model with overly bloated feature rich APIs:

“They’ve hit the wall. It’s ground-hog day all over again. Get excited. Learn a monolithic API. Start to build it. Make design mistakes. Dig hole. Make mess. Curse. Work overtime. Scratch and claw. Find silver bullet. Lather, rinse, and repeat”

We’ve all been there, done that. So whats next? Whereas OO programming was the last major shift to get past the last ‘wall’, he believe Aspect Oriented Programming (AOP) is going to be the next major change in development.
