OpenLaszlo supports Ajaxified output

I heard this was coming, but I didn't expect it so soon.

There has been some crazy, crazy work going on here in the last month or two and the result is amazing. Today at etech, we’re demoing an early alpha of OpenLaszlo’s new DHTML backend. Truth! Press Release!

Here’s a new demo showing off the goods:

• LzPix demo, Flash version
• LzPix demo, DHTML version
• LzPix demo, source code

That’s a live OpenLaszlo server, running both apps from the same source code.

Also, new shiny openlaszlo.org page, with links to the DHTML demo.

This demo definitely works best in Firefox, but it's damn impressive. It's tough to test which medium you're using if you open them side-by-side. My hats off to you OpenLaszlo Developers - well done.

RE: Marketing is the billion dollar question in open source

Dana Blankenhorn has an interesting post titled Marketing is the billion dollar question in open source. I definitely agree with this. Good marketing of a project can make it successful, and bad marketing can kill it. It really is the hardest part of being an open source developer. Sure it's fun to work on this stuff until the wee hours of the morning, but if no one (including yourself) appreciates your project (due to your lack of marketing), it really worth it? Compare that to wild enthusiasm by your users and people writing articles about your project. There's a stark contrast there.

Some of the hottest open source projects are driven by marketing. Read more (and comment) on my Virtuas blog.

Dream Bus

This is a 23-window bus, and looks to be a bit older than mine (a '66 21-window). However, it has the same paint job I'm dreamin' of. Sure is beautiful.

Upgraded to Roller 2.1

I upgraded this site to Roller 2.1 yesterday. I did encounter a few issues while upgrading, but nothing too major. If you see any issues let me know.

For the record, this blog has had 2244 entries and 7380 comments since I started it in 2002. I wonder what the highest numbers are on a Roller-based blog?

CSS Framework Design Contest

Over the past 2 weeks, I've managed to raise $900 for the CSS Framework Design Contest. Thanks to friends, AppFuse users and SourceBeat their donations. You guys rock!

With this cash, I hope to give away 3 prizes: an iPod (60GB), an iPod (30GB) and a 2GB Nano. Of course, if the winners decide they'd rather donate the money to charity, that's cool too. Any additional donations I receive I'm going to send to the Elena Steinberg Memorial Fund.

Here's the rules of the contest: Create a theme (mostly CSS, images allowed) that makes the CSS Framework look good (download source files). This framework is simply a structured bit of XHTML for page layout, and a number of CSS files for positioning. What's missing is a number of good-looking themes to make this framework look even better. I have aspirations of creating something like CSS Zen Garden - but with more of a web-application flavor.

I'll use the same submission guidelines as the CSS Zen Garder, but add that your themes should be Apache licensed. In my mind, this simply means that anyone can use your theme - they simply have to retain your contact information in a comment w/in the stylesheet itself. I'd like to distribute (or at least make available) the top themes to AppFuse users - so they aren't stuck with a single theme. In addition, it probably wouldn't be too hard to make these into Roller themes.

The CSS themes from this contest should be usable in corporate intranets, as well as customer facing applications. Sure, wacky designs are cool, but sharp and clean are better. Extra points will likely be given for themes that pretty up how forms are laid out and displayed. Ajaxian.com links to some good examples, particularly Wufoo.

I've created a CSS Design Contest project in AppFuse's JIRA - so please submit your entries there. The contest ends on March 31st, 2006 at midnight MST. After that, the winners will be decided using some sort of voting mechanism. I hope to create an application to showcase all the entries in the next week or two.

Good luck folks - may the best design win!

Spring Fundamentals in Boston almost sold out...

If you're looking to learn Spring and live near Boston, I'm coming to town on March 14th to teach our Spring Fundamentals course. We're getting pretty close to capacity, so sign up now before it's sold out!

And yes, I will be staying in Boston on Friday night for St. Patty's day. Should be a good time for sure.

MacBook Pro Battery Life

I leave my MacBook Pro at the office these days, and keep it plugged in most of the time. However, some folks have asked about battery life, so I figured I'd test it out today. I unplugged it when I got in and waited for it to sleep. 2 hours and 23 minutes. This is on par with my old PowerBook, but it's quite different from what MacRumors says (3hr 17min). I have a keyboard, mouse and 20" cinema display hooked up to it, but the display has its own power, so I doubt that effects the results.

Which Ajax enabled framework should you use as an Enterprise Java developer?

Paul Browne asks (and answers) "which Ajax enabled framework should you use as an Enterprise Java developer?":

Paul goes on to show you how he researched the Ajax-enabled Java frameworks that are currently available and gives a set of criteria he used. His conclusions?

• Use AjaxAnywhere if you need to add Ajax functionality to an existing Struts application.
• For new applications with Ajax, use AppFuse. While he recommends the Struts version, I recommend using the other flavors first (Spring MVC, WebWork, Tapestry or MyFaces).
• For the future (which I believe is what he means by medium-term), use a JSF implementation. AppFuse currently uses MyFaces, and it's likely we'll keep improving that (possibly with a Shale front-controller or some nifty things the Spring team has been adding).

James Governor:

It's not every day you get listed with a line-up like that! Like Simon Phipps commented - where should I send my resume? Looks like I owe the RedMonk guys a beer or 6.

DbUnit Tip: Turn off foreign key constraints when importing into MySQL

One of the issues I've had with using DbUnit is getting tables to load in the proper order from XML. The XML datasets I use to load table data are flat and don't really have any notion of foreign keys and such. Therefore, when you get into a situation where tables have a circular reference, using DbUnit can be a real bitch. I ran into this situation yesterday.

Luckily, I was able to figure out a solution thanks to the help of Mark Matthews. Just add "sessionVariables=FOREIGN_KEY_CHECKS=0" to your JDBC URL. Here's how the "db-load" target in AppFuse looks with this in place:

    <target name="db-load" depends="prepare"
        description="Loads the database with sample data">
        <property name="operation" value="CLEAN_INSERT"/>
        <property name="file" value="metadata/sql/sample-data.xml"/>
        <dbunit driver="${database.driver_class}"
            supportBatchStatement="false" 
            url="${database.url}&amp;sessionVariables=FOREIGN_KEY_CHECKS=0"
            userid="${database.username}" password="${database.password}">
            <operation type="${operation}" src="${file}" format="xml" transaction="true"/>
        </dbunit>

    </target>

Does your preferred database have a similar mechanism for turning off foreign key checks using the connection URL?
