The idea of setting up listener relationships between your GUI models, views, and controllers is simple enough, but grinding the same "glue" code dozens or even hundreds of times is wasteful and error-prone. JSR-295, Beans Binding, offers relief from the drudgery. In this article, John O'Conner...

Changes in Java 7 Locale

I admit that I haven't been particularly active in the i18n or Java standards bodies in the last few years. Pardon me, but I had a wild rumpus in a startup for almost 3 years, then joined Yahoo...

Java 7 on Mac OS X?

I recently installed Java 7 on my Mac OS X system. Although the installation went smoothly, I did run into one problem that might not be a big issue for you.

Encoding URLs for non-ASCII query params

NOTE: I've updated this blog to avoid "mojibake" -- garbled characters. For some reason, the word TA in TANAKA in the name query key in examples was garbled. Originally all...

Getting MarsEdit to work with java.net

I've wanted to know how to do this for over a year. Not having the time in the past, well, the task just got delayed over and over. Now I finally figured this out, and I'm sharing with you. Surely...

Writing CSV files as UTF-8 for Excel

Yesterday a coworker complained that Excel wasn't displaying a CSV (comma separated values) file correctly. Our application allows the user to send a report via email. The application provides the...

Geeky predictions for 2010

 Everyone has something to say about the past. Few can see the future. Here are my predictions for 2010!

Speculations regarding Google Chrome OS

Today's announcement of Google's Chrome OS is exciting in a few ways. I think it has implications for Java...

Link and run: Binding var and def variables

The Flex guys have enjoyed this for a long time. When I discussed JavaFX with a friend who is familiar with Flex, he shrugged the feature off, clearing unimpressed with JavaFX despite his...

JavaFX for-loop considerations

I hate to simply drop a link and run, but that's essentially what I'm doing here until others learn about my new blog Learning JavaFX.

Learning JavaFX?

Long ago, I started a series called JavaFX Learning Curve Journal. Those articles/journals were on java.sun.com at the very beginning of the JavaFX project. I recently tried to find some...

JavaFX Designer Tool...where is it?

At JavaOne 2009, Sun demonstrated a new JavaFX designer tool. You can even...

JavaOne 2009: Top 10 Sessions

Choices, choices...so many choices and so little time. JavaOne has hundreds of sessions, BOFS, and labs. There's no way to do it all, although many of you will try. Plan well, and use the JavaOne...

VisualVM: One of the best kept secrets

You update your JDK frequently to get the latest and greatest...but did you know about VisualVM. It may be one of the best kept secrets in the JDK. But now you know too!

Java upgrades UTF-8 handling

The UTF-8 encoding is easy to abuse in some ways. Or rather, sometimes people use it in unexpected ways.

Recently the Java platform received an update to reject one malformed UTF-8 encoding...

Will blog for JavaOne pass

I should be ashamed. But I'll do it again this year regardless. I'm begging for a JavaOne pass. I'm not asking for a free handout, not exactly. Instead, here's the deal:

What does Oracle mean for NetBeans?

By now you know that Oracle intends to purchase Sun. It's a welcome deal that will no doubt be approved by stockholders. It certainly has the board's approval. So let's assume that Oracle will own...

JavaFX Quick Tip: Printing to the console

Like Java, the JavaFX Script has its own println statement. You can use the println statement to print output to the console. This method has already been imported by default, so all you have to...

NetBeans 6.5 still coughs on spaces

I've been trying to slowly introduce NetBeans to my colleagues for over a year. I think they'd actually use it in our current products and projects, but NetBeans won't make it easy for us. How's...

Do we have a JavaFX Community site?

I know we have javafx.org, but I wouldn't call that a community site really. You get all the JavaFX announcements, downloads, docs...sure that's important. However, I'm not sure that makes a...

Blu-Ray may be the shortest lived, most irrelevant format ever

This week's java.net poll asks the question "What was the most important Java news of 2008?" One of the optional answers is "Blu-Ray wins format war." That's a reasonable option I suppose. Tthe...
