JDOM 1.0

Posted by daniel on September 10, 2004 at 7:58 AM PDT

Hey kids - we're there.

It's been one of those really long trips with the kids in the back asking "are we there yet" every five minutes from the moment they got in the car. And then, after a couple of hours on the road, the kids begin to understand that "we're never going to get there." Eventually they move on to other things and almost don't notice when the car pulls up in front of their destination.

That's kind of how the JDOM development ride has felt. Initially, the lists were full of people asking "when are we going to get there". There meant JDOM 1.0. Well, for those of you who have decided we're never going to get there or whose attention has drifted off, Jason Hunter announces "Pop the Champagne We just released JDOM 1.0." Congratulations Jason and thank you for your careful work over the years shepherding the development of this widely used, no longer beta, API.

Calvin Austin is nervous before the final release of J2SE 5.0 but says that it is Ready for business. He asks and answers the question "Would I run my business app server on it? Certainly. As part of our stress tests we have popular appservers and we are probably going to have to power down the machines as they won't stop.!"

, Apple recently made its zero-configuration self-networking technology, Rendezvous, available for multiple operating systems, with a Java API that can be used on all of them. In A Rendezvous With Java, a feature from MacDevCenter, Michael Brewer shows how to download the Rendezvous code from Apple's public CVS repository, build it, and package up a demo program into a double-clickable Mac application. This is a more or less code-free article, so it might be of particular interest to entry-level Java developers, as well as to those new to the Mac platform and its unique tools.

Chet Haase explains that it "is a lot faster to copy an image than to perform a complex rendering operation." He recommends using Intermediate Images. "For example, let's say you have an image of some size and you want it to be scaled to size scaleW x scaleH into some JComponent. You could do this in your paintComponent() method [and] cause Java2D to scale the image every time through this function (assuming your original image is not actually at size scaleW x scaleH). You could, instead, use the Intermediate Image approach, where you create an image of the appropriate size, scale the original image to that new temporary image, and then do a simple copy from that temporary image."

Jonathan Simon opens the discussion about The Dream Language in

Forums
. He notes that "Java is only mildly hackable. Swing components, while extremely flexible, have a lot of private, and package protected variables, and code is split sometimes arbitrarily between the UI and the View classes. I usually end up copying the src of some class or another and hacking (in the bad context) my own copy of it. I don't really consider that a hackable (in the good context) language."

John M replies to the comment "On the other hand, I could see an optimal unified platform -- a group of languages that all work together, each with a specific purpose and intent. Have you checked out the Parrot VM work that is being spearheaded by the Perl folks?"
