Raible Designs

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!

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).

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?

Why I like Tomcat 5.5.12 better than Tomcat 5.5.15

Roller on Geronimo

Jeff has posted a nice tutorial showing how to run Roller on Geronimo. Note that he's using a HEAD build of Geronimo, so you might have to build Geronimo yourself or wait for the next release. I've heard rumors the next release will ship with a Web-only version (i.e. Tomcat and JMS), so that might be a good fit for Roller. As for pre-compiling JSPs, that's on my to do list.

There's been a few "how to run Roller (or AppFuse)" on X server lately. IMO, the best howto is no howto - it just works. I recently tried AppFuse 1.9 on JOnAS and it ran w/o any changes. Since it uses a Spring-managed connection pool and doesn't require any server configuration, this is how things should work. I've had similar results with AppFuse on Jetty and JBoss (and Tomcat of course).

MacBook Pro and Wireless

The only major issue I've had so far with my MacBook Pro is wireless connectivity. It works fine at my office, works great at Starbucks, but not at home. My router is a Netgear WGT624.

The Netgear works flawlessly with my Windows XP Desktop (HP Pavilion 1250n) and PowerBook G4. It works with no password, 40-bit WEP and 128-bit WEP. But not with the MacBook Pro. Is there something special I have to set on my router for it to work with the MacBook Pro?

I posted this question on the Apple Discussion forums yesterday (which appear to be powered by Jive Forums). The response? Crickets. Oh well, I think I'll just leave my MacBook at the office and ignore this issue for now.

Update: Looks like Apple is aware of many issues with the MacBook Pro. Hat tip to Jeff for the article.

Smashed Fingers

Today we took the kids to Dave & Buster's for lunch. They're not quite old enough, but they do good. Abbie and I race cars and she can't even touch the gas. After a few seconds of waiting, her car takes off and she's driving - hooting and hollering the whole time. Jack isn't quite tall enough - he can peer over the edge and see a bunch of coins in the machine - but has no idea what it does. He does know that the machine takes coins - and loves putting them in. When he won 100+ tickets today, he was ecstatic - pulling the tickets out and giggling to himself the whole time.

I carried both kids to the car on the way out. We have a Honda Odyssey mini-van (they might be cheesy, but they make awesome cars - spoken like a true dad, eh?). Holly opened the door with the remote. It stopped after opening a few inches - and I reached to open it manually. As soon as I got my fingers around the door, it shut. Youch! I screamed like a little girl. After a few seconds, Holly was smart enough to open the front door and I pulled them out. No dropped kids, which was pretty impressive. It's been a couple hours since then. It was only two fingers, but one is still numb. The good news is I'm still able to type - but they're still throbbing.

MacBook Pro: Kicking ass and taking names

I received my MacBook Pro this morning, and I've spent the day setting it up, doing some development and running some performance comparisons. The setup was easy: I just booted my PowerBook into Firewire mode and copied over all the files I needed. Everything works for the most part. I did have some issues with IDEA and Eclipse, but got both working after doing a few try and try-again shenanigans. Eclipse was crashing when I'd browse to set my workspace; typing it in manually fixed the problem. IDEA hung the first time I opened it; killing it and restarting fixed the problem.

As far as performance, this thing fricken' rocks! Safari launches in under a second and you're browsing before the dock icons hits the top of its first bounce. Firefox is a different story (likely b/c it hasn't been compiled for x86) - it takes 10 seconds to launch. The good news is once it's up, there doesn't seem to be any performance issues. Safari is amazing though - the speed does wonders for GMail and it actually feels like a desktop application.

When I mentioned yesterday that I was going to compare the MacBook to my desktop, Rob Williams said it wasn't a fair comparison. I agree - but I really wanted this machine to be the best machine I could possibly buy. With my (very unofficial) performance tests, it appears like it is. It's faster than my dual-core AMD 64 desktop machine that has 3 GB of RAM. Now, I have had the desktop for a couple months, so it's possible I'm suffering from OS Rot, but still - it's impressive it keeps up. Here are the numbers from my Performance Comparisons page:

For the tests below, I used Java version "1.5.0_06" and had the following variables set: JAVA_OPTS=Xms256M -Xmx384M, $ANT_OPTS=-Xmx256m. I used the CVS version of AppFuse (1.9.1-dev).

A couple of interesting things to note:

• When I first got my desktop, it's numbers were 00:14 for "ant clean package-web" and 01:29 for "ant setup test-all". The MacBook Pro? 00:12 and 01:28. The Windows box had 1 GB of RAM when I ran those tests, but no matter how I tweaked the memory settings once I put 3 GB of RAM in, I've never gotten better numbers.
• My PowerBook has been dog slow for several months now. When looking up the OS X version on it - I noticed it lists the memory as 512 MB. WTF?! I've had 1 GB in it every since I first bought it! What happened? Did half my RAM go bad or did someone steal half of it during a repair? Oh well, at least I now know the reason it was so damn slow.

Conclusion: The MacBook Pro is one of the best machines you can buy (laptop or desktop) for Java development. As for the battery life? I'm still doing the "calibration", so I'm not quite sure. Nor do I care - I plan on having this thing hooked up to my 20" cinema display that Virtuas was kind enough to get for me. The display combined with a mouse, keyboard and iCurve is a very nice setup.

Update: I pulled out the memory from my PowerBook and put it back in. Upon reboot, it resulted in the correct (1 GB) memory setting. The numbers above appear to be accurate regardless. I ran some tests again and times were actually slower (maybe because I'm on battery power).

[ANN] Equinox 1.6 Released

For a good story of how Equinox helps, see Wayland Chan's Equinox to the rescue blog post.

This release's major new features are Tapestry 4.0 and WebWork 2.2.1 upgrades. In addition, I changed to use Maven's Standard Directory Layout. It makes IDE and using Maven plugins much easier, so it's a natural progression.

This release does not contain Maven support for running the integration tests with Cargo. This is because Cargo still seems a lot more complicated with Maven than with Ant. Hopefully I'll be able to figure out an easy way to get test-all functionality with Maven and Cargo in the next release.

All of the frameworks used in Equinox, as well as its build/test system is explained in Spring Live. A summary of the changes are below (detailed release notes can be found in JIRA):

• Added custom exception page for Tapestry, as well as tapestry-flash.
• Changed birthday date input to use WebWork's DatePicker component.
• Added support for pre-compiling JSPs when building with Maven (on by default).
• Added createDatabaseIfNotExist=true to jdbc.properties.mysql to auto-create the database when using MySQL.
• Changed classes that extend *SpringContextTests to use AUTOWIRE_BY_NAME so more than one instance of an interface is supported.
• Dependent packages upgraded:
  • Cargo 0.7
  • DisplayTag 1.1
  • Hibernate 3.1.2
  • Scriptaculous 1.5.2
  • Tapestry 4.0
  • WebTest build 1168
  • WebWork 2.2.1

Download. For more information about installing the various options, see the README.txt file.

Demos:

• Spring
• JSF
• Struts
• Tapestry
• WebWork

Known Issues: The Tapestry-Flash JAR was built with JDK 1.5 - so you'll need JDK 5 to run the Tapestry version. Howard Lewis Ship said he'd fix this tonight or tomorrow. Also, if you're on Unix, you'll need to run "ant fixcrlf" before you install anything. Finally, downloading dependencies might not work the first time. Running the "ant" or "mvn" command multiple times usually solves the problem.

See the roadmap for what's coming in the next release.
