Jetty 6 Maven Plugin now works with SiteMesh (and Equinox)

The 1.6 version of Equinox contains commented-out settings for Maven 2 Jetty Plugin. The reason these are commented-out is because this plugin didn't work with SiteMesh at the time. I checked again today, and it looks like they got it fixed. See Brett's post titled Developing with Jetty: Where Have You Been All My Life? to see why this plugin is so cool.

Using this plugin (or the JettyLauncher in Eclipse) makes it pretty damn easy to do develop Java webapps. There's no longer a deploy cycle, just save and refresh your browser. IMO, it's almost as good as using a scripting language or developing with HTML/CSS/JavaScript.

I'd love to see someone develop a TomcatLauncher, a WinstoneLauncher and Maven 2 Plugins for both. AppFuse works with Winstone 0.8.1 (a wicked fast servlet container with a good story behind its name).

In other Jetty news, Jan Bartel posted a nice tutorial today titled How To Use JOTM as the XA Transaction Manager in Jetty6.

TSSJS BOF: Web Framework Sweet Spots

I'm leading a BOF at this year's TSS Java Symposium titled Web Framework Sweet Spots.

The objective of this BOF is to discuss the various open source web frameworks and what each does well. Matt kicks off the discussion by highlighting the good features of various frameworks, (results of pre-conference discussions with various framework authors to get their opinions on what problems their framework solves best) as well as debunk some myths based on audience members real-world experiences.

Yesterday, I sent an e-mail the authors of the most popular web frameworks in JavaLand. In my opinion, these are (in alphabetical order): Cocoon, JSF, RIFE, Seam, Spring MVC, Spring Web Flow, Struts, Trails, Tapestry, WebWork and Wicket. If your framework isn't on this list, I'm sorry. If you can prove to me that yours is more popular than one of the ones listed here, I'll send you the questionnaire and add you to the list. I've received a few responses, and I doubt all authors will respond, so there might be some room.

If you're going to be at Caesar's Palace for TSSJS 2006, I invite you to stop by on Friday night at 6:30. I've asked the TechTarget folks several times about getting beer served at this BOF, but they keep ignoring the question. I think it's time to contact Caesar's - since it is legal to have a beer pretty much anywhere in Vegas.

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.

For inspiration, you might checkout Open Web Design and Open Source Web Design.

Good luck folks - may the best design win!

[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.

Upgrading Equinox to WebWork 2.2.1

In addition to upgrading Tapestry last week, I also upgraded Equinox to WebWork 2.2.1 (from 2.1.5). The commit log can be found on Fisheye. The changes I had to make were pretty minor:

• WebWork 2.2.1 easily integrates with Spring - you just need to add webwork.objectFactory=spring to your webwork.properties file. This isn't a whole lot different from 2.1.5, except that you can get rid of the SpringObjectFactoryListener from web.xml.
• ServletDispatcher has been deprecated in favor of FilterDispatcher - which should map to <url-pattern>/*</url-pattern>. Using a filter for the controller is an obvious improvement, and it's pretty slick how WebWork can now add CSS and JavaScript to your pages on-the-fly.
• WebWork now has a <ww:datepicker> component which makes it possible to do easily do popup calendars like you can with Tapestry and JSF. Unfortunately, it seems you still can't set a global date format using a ResourceBundle.
• AltSyntax is on my default, which means you'll need to change "'literal string'" to "literal string" and "variable" to "%{variable}". This is much easier to read and a welcome change. It's unfortunate that ${} can't be used, but that's JSP's fault, not WebWork's.
• FreeMarker is required, even if you're just using JSP. This is because the JSP tags' HTML is generated using FreeMarker templates (I think).
• The taglib URI has changed from "webwork" to "/webwork". I wonder why they don't use the full URL like most tag libraries?
• Exception mappings have been added so you can easily map a particular exception to a specific view. This allowed me to remove a custom interceptor I'd previously wrote.
• The DTD for xwork.xml has changed from xwork-1.0.dtd to xwork-1.1.1.dtd.
• The only issues I found were that the validator interceptor makes it difficult to override "excludeMethods" and client-side validation renders duplicate messages when you click submit multiple times.
• When I deployed the latest Equinox demo to Contegix, we had some issues with the stylesheet the datepicker stuffs in the <head>. Basically, mod_caucho 3.0.14 wasn't returning the proper content-type for the stylesheet (even though it was for the rest). Upgrading to Resin 3.0.17 with mod_proxy fixed the problem.

Hopefully this helps you upgrade to WebWork 2.2.1.

Upgrading Equinox to Tapestry 4.0

Last week, I upgraded Equinox from Tapestry 3.0.3 to Tapestry 4.0. The commit log can be found on Fisheye. Here are some details that might help you upgrade.

• Tapestry 4.0 doesn't support Spring out of the box. This was surprising to me b/c one of the advertised features of Tapestry 4.0 (or Hivemind actually) was native Spring support. Luckily, Howard released the tapestry-spring project which solves this problem. Dropping the JAR in your classpath is enough to get built-in integration. It'd be nice to see this library become part of tapestry (possibly in the tapestry-contrib.jar).
• Tapestry-Flash makes it easy to do success messages when redirecting. Furthermore, it's nice to see how to do redirecting w/o throwing a PageRedirectException.
• PageRenderListener has changed to PageBeginRenderListener.
• When using <inject> for a property, I had to remove any public abstract void setXXX methods as I got an error otherwise. Luckily, the error message told me exactly what to do.
• Injecting dependencies during testing is fairly simple using the Creator class. Equinox's UserFormTest.java has a good example of this. I did have to create a MockRequestCycle and a MockPageService, but both were pretty easy to write.
• Friendly URLs are much easier to implement in Tapestry 4.0. However, Tapestry still doesn't allow you to use the same extension for everything - so I ended up with .html, .direct, .sdirect and .svc extensions. I'd prefer a single extension, but oh well.
• You'll need to change all your *.page files to use the new 4.0 DTD. I don't think this is absolutely necessary, but it does simplify things.
• As part of the 4.0 DTD, <property-specification> has changed to <property> and the "type" attribute is not allowed (b/c it's inferred using reflection I assume). In addition, <binding name="foo" expression="bar"> has changed to <binding name="foo" value="bar"> and <context-asset> has changed to <asset>. Also, <message-binding> has been removed in favor of <binding>. The userForm.page diff shows detailed changes.
• @Conditional has changed to @If.
• The issue where Tapestry sets the focus on the first required field still occurs. An easy workaround is to make the first field required.
• The @DatePicker component has changed from using the "format" attribute to using the "translator" attribute for formatting dates. The popup calendar also seems to have changed - I had to add new CSS rule to colorize the header properly.

Hopefully this simplifies your Tapestry 4.0 upgrade.

[CSS Fundraiser] Brrrrrrrr

At 14°F, it was definitely a cold ride to work this morning. It took about a mile and a half before my face when numb. Then I stopped to snap some pictures, which made my fingers go numb. However, the sun was out and it is a beautiful morning in Denver.

Why am I doing this? To raise money for a CSS Design contest.

Tuesday Morning Update: Last night's ride home was pretty warm - 35°F. This morning's ride was fairly nice too (31°F). Here's proof from last night.

Fundraiser for CSS Framework Design Contest

A week ago, I received a $250 donation for "AppFuse Development". This is a significant amount of cash, and unfortunately the committers can't do a "beer at the local pub". We've decided that a good thing to do with the money is to use it to buy a prize for a CSS Framework Design Contest. The AppFuse Logo Contest went well, but I also gave away an iPod to the winner.

This contest will be a bit different. First of all, the CSS Framework is not AppFuse-specific at all. It's just 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 templates 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. Hopefully we can use the same submission guidelines as well as offer the contest's themes for anyone to use. 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.

I hope to start this contest as soon as I've raised some funds for good prizes. Of course, donating good prizes is most welcome too. In order to provide some motivation, I'm going to do something that will hopefully inspire you to donate. It's butt-ass cold in Denver this week, and it's not warming up anytime soon. Here's the current forecast from the local news channel:

So to try and raise money, I'm going to ride my bike to work every day this week. Will this inspire folks to donate? I don't know, but it's worth a try. I'll try to be in the office by 9, and won't be home before 5. This should ensure that it's good and cold out. Furthermore, I'll blog about my ride everyday, and hopefully snap some pictures as well. It's supposed to snow tonight, so this should be good.

Remember, anything will help - and all donations will go to a good cause. I plan on starting the actual design contest next week sometime. Now it's time to donate using the button below - and watch me freeze my ass off this week!

If you want to be more productive with IDEA, Patrick Lightbody has a good suggestion in IDEA Live Templates: more powerful than you think. Now where's the list of the built-in live templates? Does Eclipse have a similar feature?

Spring Workshops from Virtuas

I'm pleased to announce that my company, Virtuas, has decided to start offering public workshops for many prominent open source projects. These include Spring, Geronimo, Tomcat, Hibernate and JSF/MyFaces.

I'll be teaching the first Spring course in Denver February 21st - 24th, followed by one in Boston in mid-March. It should be a fun class, especially since I'm adding a bunch of stuff regarding Spring 2.0. Since I know you're going to ask the price -- and it's not posted on virtuas.com -- it's $2,495 per person for 1-4 people from the same company/group/etc., $1,995 per person for five or more people.

In other Virtuas news, we've recently signed partnership agreements with IBM and Covalent. We also re-worked our site with Andreas Viklund's "andreas08" theme from Open Source Web Design. Thanks to the power of Drupal, all we had to do to change the whole site was modify one PHP template and one CSS file. Thanks to both Andreas and Drupal for vastly simplifying our new look-n-feel.

Update: It looks like Andreas's theme has been made into a Drupal theme. Nice.
