My IDE is even more helpful than before, now. Because I've been playing with the IDE's JGlassPane (as a result of some questions about this), I am now ready for winter: Don't say I didn't warn you. I have found Chet and Romain's book very helpful in this instance too. Somewhere I read that their book is supposedly aimed at advanced Swing developers. Well, if that's true, why is there a detailed section on Threading (amongst several other interesting intro topics) at the start...

There is a very cool recent blog entry by Milan Kuchtiak, called JAX-WS Tutorial: Working With Binary Data. Milan is one of the NetBeans engineers in the Java EE team, and currently on the Web Services Core team, responsible for several web features in the IDE, such as the web.xml editor, among many others. Milan's blog entry shows you how to use the IDE to create a web application that exposes a web service that delegates to a session bean to provide photos. The photos are...

To use Schliemann in the context of an existing data object, you need to specify that your NBS file will not cause your document to be handled by the Schliemann data object. Instead, you want your own data object to be loaded when a document of your MIME type is opened. So the line in bold is needed in the layer file: <folder name="Editors"> <folder name="text"> <folder name="x-java-jar-manifest"><attr name="createDataObject" boolvalue="false"/> <file...

It may seem counterintuitive that I am excited about this, after all my blogging about the joys of paperlessness, but there's something really cool that happened in the last few days on the NetBeans Platform—vastly enhanced and simplified print capabilities! :-) Not that I've actually printed anything as a result of this, seeing as I'm not connected to a printer because of aforementioned paperlessness. However, part of these enhancements include out-of-the-box support for a...

For a cool life with Java and Swing, take one computer and two books. Start up the first, and open the others. Start reading. Then apply what you read. Satisfaction guaranteed. Here's a summary, showing the two books in the context in which they were meant to be used: On Amazon, you can buy the two together at a special price. At Sun Microsystems Press, you can buy them at a 30% discount. The sunglasses you'll have to get yourself somewhere. Laptop too. And for examples of how...

Comments at the end of Paperless Office: One Month Later indicate that people want a set of "best practices" for maintaining a paperless office. After all, the maintaining part is the point. Establishing a paperless office is relatively simple, if not without a certain level of discomfort. (Read Nirvana is a Paperless Office for notes on how to establish a paperless office.) The maintaining part is where everything falls apart, or not, as the case may be. Before looking at...

Chet and Romain's "Filthy Rich Clients" teaches you how to create stunning visual and animated effects with Swing and Java 2D. By the end, you'll know all about graphics and animation fundamentals in Java, as well as advanced rendering techniques. Interestingly, the book's website, http://www.filthyrichclients.org/, provides a page from which you can download all the samples discussed in the book. And... all those samples, 82 in fact, are NetBeans projects! They're all quite...

Yup... a very happy-looking visual game designer for mobile phones, with emulator support! You get it with all the rest of the mobility features, no additional plugins to install, no additional steps to take, it'a all there out of the box. Wow, cool. What a surprise, who'd have thought that NetBeans IDE even provides advanced tooling for game designers. Not me, anyway. A tutorial on creating games for mobile phones can be found here. The above screenshot is of... the sample...

Recently I've been in touch with Björn Lietz-Spendig. Björn is German and lives in the south of France. He's using the Schliemann Framework to create an editor for the D programming language and also for its scripting language MiniD (written by Jarrett Billingsley). I asked him a few questions about this development work he's doing. He had some problems getting code folding to work and in this blog entry I will show him (and others who might be interested) how to iteratively...
