There's nothing like finishing up a training class

There's few feelings as great as finishing up a training class. The aches and pains that sneak into one's bones after talking and standing for 4 straight days is amazing. This week, I've been in Milwaukee, training a bunch of folks on Spring and particularly the new features in Spring 2.0. I had a full classroom this week, 18 students, and a number of them where PHP developers moving to Java. I had a tough time convincing them that web development with Java was easier, but hopefully they enjoyed the class anyway.

Now I'm sitting in the Milwaukee Airport, getting ready to fly back to Denver. Once I arrive in Denver, I have 2 hours before my flight leaves for Vegas. Hopefully I can catch a couple naps in flight and recoup before tonight's crazy night in Vegas begins.

As far as airport security, it was easy getting through in Denver, but they stripped me of my toothpaste and hair gel here in Milwaukee. Oh well, I shoulda known.

Integrating Hibernate Validator with Spring MVC

Remember when I wrote about Better client-side validation with Prototype back in May? Ted Bergeron responded to my post with the following comment:

Now that I am using Hibernate Annotations Validator, I stopped using commons validator. You can use the hibernate validator without using hibernate for persistence. I wrote some jsp 2.0 tag files to handle binding my form fields with spring mvc, and I use reflection to check for the validation annotations. This makes it no work to have a js calendar for all Date fields, or have class="required" added to all fields that have a @NotNull annotation. I'd be happy to send you the code for appfuse 2.0.

Ted followed up by sending me the code. I took a look at it, and reviewed a well-written PDF he'd written for his work. I told him he should publish it as an article, hooked him up with some folks at IBM developerWorks - and voila! Ted's article, titled Hibernate can meet your validation needs was published yesterday. Nice work Ted!

I'm looking forward to trying to leverage Hibernate Validation annotations for all the web frameworks in AppFuse. Should be interesting hacking into the cores of the frameworks to modify how their validation engines work.

Integrating Compass with AppFuse and the Display Tag

ChenRanHow has written up a detailed tutorial on how to integrate Compass with AppFuse and the Display Tag. From his mailing list post:

• Part 0. Overview of the practice
• Part 1. Setup env, add Compass and related library to AppFuse
• Part 2. Create ant tasks for create and delete index
• Part 3. Use annotation to make Compass resource mapping
• Part 4. Create Struts action to perform search
• Part 5. Make DisplayTag work with Compass

Thanks ChenRanHow!

Another great tutorial was recently written by Luciano Fiandesio. If you're looking to use Quartz, checkout Luciano's (well styled) AppFuse and Quartz tutorial.

In other AppFuse news, FanYang has started translating the documentation to Japanese, Mike McMahon has converted the appfuse-hibernate module to annotations, CruiseControl is continually testing, Mike Horwitz has solved most of the "Maven doesn't read a WARs dependencies" issue, and Scott Ryan is still hard at work on the code generation plugin. Even better - we've asked Scott to come aboard as a committer and he's accepted. Welcome aboard Scott - we appreciate all the work you're doing.

As far as progress on AppFuse 2.0, we're almost done with the Maven 2 conversion. The only thing left is figuring out how to get Mike's maven-warpath-plugin to hook into the Eclipse and IDEA plugins to they generate project files correctly. After that, it's time to start on documentation. I'm still torn on if we should use Confluence or DocBook. However, after looking at Spring's documentation for the past week, I think DocBook is probably the better choice. Then again, Stripes' Confluence Wiki looks nice and organized.

What do you think? What's the best way to write documentation for an open source project? Which system do you prefer to read? From experience, I prefer reading Spring's documentation over trying to find stuff in WebWork's wiki.

We've had great success with AppFuse users contributing to the documentation via a wiki, and I'd hate to create a documentation system that gets away from that. Maybe a DocBook/Confluence combination is the way to go? It looks like the CeltiXFire folks are having a similar debate.

GlassFish Numbers Fudging

Remember when I thought Sun/java.net was trying to make GlassFish look more popular than it is? It looks like they took it up a notch in August. Not only do they have the top spot in "most accesses", but they have the top 2 spots!

Isn't it possible to automate these stats instead of using a spreadsheet?

Continuum vs. CruiseControl for Maven 2

I spent some time this past weekend getting automated builds setup for AppFuse 2. Since the project now uses Maven 2, I figured I'd give Continuum a try. I pointed it at my pom.xml in SVN and expected everything to work out-of-the-box. No dice. It seems that Continuum reads the artifactIds instead of the module names for sub-project resolution. To workaround this issue, I'd basically have to rename all my sub-projects to have an "appfuse-" prefix. Doesn't that violate the whole DRY principle? Sure, there's projects that do this, but there's others that don't.

Since I didn't feel like renaming the modules/directories in SVN, I gave CruiseControl a try instead. It took a bit of elbow grease on my part, but I ended up with a config.xml file that works splendidly. It seems somewhat ironic to me that the CruiseControl works better with Maven 2 than Continuum does.

The neighborhood just keeps getting better

When Julie, Abbie and I first moved to our neighborhood, Julie was a little apprehensive. She liked living out in the burbs, and we were planning on living here for a few months while another house was being built in The Ranch. Meanwhile, I loved the neighborhood. I went to school at DU (a mere 8 blocks away) and considered the area my "old stomping grounds."

After a couple months, The Ranch house fell through (price went up 60K) and we decided to double the size of our house. We rented the house next door while ours was being built. Last year, that house was leveled and a nice 2-story, full basement house was put in. It sold a couple months ago for $750K. When we remodeled our house, we did it because we needed the space, not because we thought its value would skyrocket.

Today, I couldn't ask for a better location to live in. I was disappointed when the excellent Italian restaurant (literally 50 feet from our house) was replaced with Little India. However, I love Indian food and we've grown to love the new place. The wine tastings (Wednesdays and Fridays) at Little's Liquors are great, and the fact that I can take out the trash and pick up a bottle of wine in under a minute is phenomenal. The fact that Safeway is 1.5 blocks away is great, we walk there several times per week. Heck, even the first Chipotle ever built is only 6 blocks away. Not to mention Jerusalem's, the best Middle-Eastern food in town.

My motivation for writing this post is because a new Sushi place has moved into our neighborhood. Julie mentioned it last week, and I had a chance to check it out today. I was very impressed when I walked in and discovered it was a John Hollys. I've only eaten at one John Hollys (near Park Meadows Mall), but it was excellent. Needless today, lunch was scrumptious today and I'm looking forward to eating there again. The Sushi Den is pretty close by as well, but it's probably a mile away - unlike John Hollys at a 1/2 block.

AppFuse 2.0 Status

Last week I managed to get AppFuse to compile with Maven 2, this week I got all the tests passing. This week, I struggled with Maven's WAR dependencies and how AppFuse will be used by end-users. It was frustrating, but I think I got most everything figured out. Unfortunately, there's still many issues to be sorted out.[Read More]

Label placement in web forms

From Swapnonil Mukherjee:

Matteo Penzo has published an excellent article about the placement and alignment of labels in data entry forms. His research, though much more scientific and thorough, confirms what I had said earlier, about the importance of right aligning form labels.

In AppFuse 1.9.2, we added support for the CSS Framework and Wufoo-style forms. The new form layout appears to satisfy many of Matteo's suggestions. The only things we aren't doing are: 1) we're using bold labels instead of plain text and 2) we're using labels for drop-downs, instead of making the first element the label. I suppose the bold labels isn't much of an issue b/c we're not using heavy input borders. As for labels and <select> elements, I think the way we're doing things is good enough. If it works for Wufoo, it works for us!

High Performing Java Web Frameworks

Steven Haines appears to be gearing up for a showdown among Java web frameworks. In his Web Frameworks article (found via dzone), Steven notes the following:

He goes on to say that he's planning on comparing a number of web frameworks, and his study will give special attention to how these frameworks perform. He'll be comparing Struts 1.x, Struts 2.x, Shale and Spring MVC. If you think your framework can compete, Steven invites you to send him an e-mail.

If anyone has a compelling reason why we should add an additional framework, please contact me and I will be glad to consider it in this endeavor.

I'm looking forward to reading Steven's articles, I just hope I can find them again when they're published.

AppFuse 2.0 Status

I managed to get most of AppFuse's code moved over to a Maven 2 structure this week. I have tests working in the hibernate/ibatis projects, as well as the service project, but not in the web tier projects yet. I do have everything compiling though.

If you'd like to review any of the work done thus far, I've uploaded my latest work to:

http://static.appfuse.org/downloads/appfuse2-20060817.zip

The major issue I've encountered to date can be reviewed on the Maven user mailing list. If you happen to try things out, the best thing to do is post feedback to the dev list. I'm considering another device-free weekend, so I may not respond until Monday.
