RE: Which is the Hottest Java Web Framework? The "Break it Down" Blog has a lengthy post on Which is the Hottest Java Web Framework? Or Maybe Not Java? Comparing Java Web Frameworks is hard because so many people are passionate about the framework they know best. Add a couple more like Flex and Ruby on Rails and its downright difficult. Nevertheless, this post is good in that it contains a lot of pretty trend graphs and it looks like the author has done some good research. It's likely the folks that will scream foul are the ones that did poor in the comparison (Tapestry and Stripes, I'm talking about you).

Surprising among the top Java Web Frameworks is the rise of Struts 2:

Google Trends Graph

To quote:

Which is much more interesting I think is how Wicket adoption has stayed almost flat while Struts 2 adoption has spiked. Spring MVC/WebFlow seems to be going no where fast and racing JBoss Seam there.

The popularity of Struts 2 really caught me off guard with it being quite a bit different from Struts 1, I figured it got thrown into the "just another web framework" category, but I guess there is something in a name and it's doing quite well.

Regardless of what you think of the post and trends, you have to appreciate the amount of time the author put into it. Posted in Java at Jun 10 2008, 10:39:08 PM MDT 14 Comments

David Sachdev on Web Framework Proliferation David Sachdev left the following comment in my post about the Java Web Framework Smackdown at TSSJS in Vegas:

The number of web frameworks out there is just astonishing, and in alot of ways I think that there is need for some consolidation in some way, shape or form. If you work in the Java world there is a sense of consolidation in the ORM space these days with JPA (the Java Persistence API). Sure if you are working strictly with JPA it is a bit more limiting then working directly with Hibernate, iBatis, or TopLink - but you no longer worry that you have made a critical misstep in your architecture by tying yourself do a particular ORM implementation. Similarly Spring gives you that similar "loosely coupled" feel that if Google's Guice because appealing to you, you don't feel like you've wasted all your framework foo on Spring. But web frameworks....that's another story.

I think if you had asked me a few months ago, I would have told you that the industry is promoting JSF (Java Server Faces). Everything from support in the IDEs to the availability of AJAX frameworks...and of course a flexible life cycle that allows for alternate implementations and various code to plug or be weaved in to the life cycle. And that while JSF on its own left quite a bit to be desired, the JBoss Seam project really has filled in the gaps in JSF, and in fact brought Java web development closer in agility to the Rails and Grails of the world that tout quickly built and deployed web applications.

But the thing that you continue to hear is that programming in JSF is painful. And you hear that EVERYONE used to use Struts. And that it is time to move past Struts. And given that, you have to consider Webwork and the merger of Struts2 into that framework - and their claims of rapid development. But you also have to consider Spring WebFlow and how that may help solve your JSF ills given that everyone is building off of the Spring Framework and they have been so good about keeping the framework updated and integrating the best of what is out there while innovating themselves. And then if you are looking at Spring WebFlow, you kinda have to go "Wait, but what about Spring MVC?"

Given its age, you might quickly dismiss Spring MVC until you realize that Grails is build upon it. Grails, that web platform that every java developer is either working with, or intends to work with soon. (Come on, you all have made the Ruby/Rails, Groovy/Grails, JRuby decision in favor of G2, right? I mean all the flexibility of what is out there in the Java world on top of the JVM, with a language that doesn't suck the life outta you....) And then you have to wonder that if you build upon Spring MVC as well as using Groovy and Grails where appropriate, might you be able to make that killer app in half the time.

But wait, you didn't think your choices were nearly that simple did you? There is this wonderful software company out in Mountain View that we need to pay attention too. In Google We Trust, right? And even if you don't worship at the Temple of the G (TOTG) like Sprout, you don't want to ignore them. And, if you've looked at the Google Web Toolkit (GWT) and weren't at least slightly impressed, I would be surprised. And if you are looking at the GWT, you can't totally ignore Yahoo's YUI - maybe with some of the what Prototype, Scriptaculous, or DoJo offer you. And then someone will come over and point out Echo2 to you, and well you have to admit, their demo looks nice. And well, there is Adobe Flex, and OpenLaszlo - I mean after all isn't Web 2.0 all about Rich Internet Applications. And surely you've heard that the performance of Swing is so much better these days and the "power of the modern Java applet"

So at the end of it all, you've got yourself alot of R&D to do, and just as you thing you've got a good grasp for the offerings out there, new and improved versions are out. And don't worry, someone else is also busy working on a new and greater web framework that you have to consider.

Wow - that's quite a mouthful David. Well written!

Java Web Framework Smackdown at TSSJS in Vegas This year's TSSJS is starting to look like an excellent conference. I'm particularly excited to be moderating the following Expert Panel.

Java Web Framework Smackdown: Struts 2, Spring MVC, Grails, Seam/JSF and Wicket
The leading advocates of today's popular Web frameworks will duel under the Vegas Lights. Come and learn when to use your favorite framework and to see if it can live up to its hype.

We're talking about productivity, scalability and maintainability of Java-based Web applications. The emerging trend is that simplicity is better and productivity matters. Furthermore, if maintainability is the most costly part of any application -- how do these frameworks perform?

Attend if you're a Java Web developer, or if you simply like good entertainment. A working knowledge of the popular Java Web framework options will make this session more fun. If you haven't worked with any framework, come and learn who has the best spokesman.

The Venetian I plan on bringing the boxing bell from OSCON 2005 to make this session one of the best in the show. I'll be coming up with a list of questions for these experts in the next couple of months. In the meantime, if you have any suggestions, please let me know.

With a venue like The Venetian, why wouldn't you go? ;-) Posted in Java at Jan 11 2008, 12:06:24 PM MST 19 Comments

Xebia Web Framework Contest I found an interesting blog post today about a contest (English translation) a French company (Xebia) had with some Java web frameworks.

4 teams have developed the same web application, each with a framework (very) different. The frameworks used were:

  • Struts 2
  • Google Web ToolKit
  • Wicket
  • My Faces (JSF)

Overall, I think it's a good summary of the strengths and weaknesses of the various frameworks. Posted in Java at Oct 30 2007, 09:32:34 AM MDT 8 Comments

Does Struts 2 suck? As far as I can tell, Struts 2 sucks. To be fair, so does Stripes. Why? Because there's no developer feedback for invalid properties or OGNL Expressions. What does this mean? It means if you fat-finger a property name, nothing happens. The OGNL exception is swallowed and you never know you did anything wrong. Furthermore, no one seems to care. The XWork folks will help you build, but not solve the problem. This seems like a major deal-breaker to me, However, I also believe it can be fixed - so maybe there's hope.

To demonstrate the problem, I did an experiment. I used the "user details" page in AppFuse Light to fat-finger a property name for the following frameworks: Struts 1, WebWork, Struts 2, JSF, Spring MVC, Stripes, Tapestry and Wicket. First, I tried changing the "lastName" property to "LastName" to see if the framework's property evaluation was case-sensitive. I found that with WebWork/Struts 2, Stripes and Tapestry, the property is not case-sensitive. I prefer case-sensitivity, but maybe that's because I prefer Unix over Windows.

The 2nd thing I tried was changing "lastName" to "pastName" to see if I'd get an error. An error occurred for all the frameworks mentioned, except for WebWork/Struts 2 and Stripes. This makes me believe these frameworks suck. The both use OGNL, so they could blame it on that, but Tapestry uses OGNL and it presents an error message. After this small experiment, my conclusion is the following frameworks have the best developer feedback:

  • Struts 1
  • JSF
  • Spring MVC
  • Tapestry
  • Wicket*

* Wicket seems like it needs some work as all it presents is "Internal Error" and makes you dig through your log files to find the problem.

Without good developer feedback, how can you have good productivity?

Dear Struts 2 and Stripes Developers,

What do you think about improving your error messages for invalid properties and expressions? Is this a feature you think you could add? We'd love it if you did.

Sincerely,

Your Users

Click here for some screenshots of how a fat-fingered property looks in various frameworks:

Update: Stripes doesn't suck and Wicket has excellent error reporting. See my comment below for more details.

Update 2: I've created a patch to (hopefully) solve this issue in XWork. If you have any feedback on ways to improve this patch, I'd love to hear about it.

AppFuse 2.0 RC1 Released The AppFuse Team is pleased to announce the release of AppFuse 2.0 RC1! This release marks a huge step in the march to releasing AppFuse 2.0. This release puts the finishing touches on the AppFuse Maven Plugin (AMP), which offers CRUD generation, as well as the ability to change AppFuse from "embedded mode" to "full source" (like 1.x). In addition, we've addressed over 100 issues in preparation for the final 2.0 release. We hope to fix any bugs related to this release and release 2.0 Final in the next week or two.

The videos still represent how M5 works, but things have been simplified (now you don't need to run appfuse:install after appfuse:gen).

AppFuse 2.0 is available as a Maven archetype. For information on creating a new project using this release, please see the QuickStart Guide or the Hello World video.

If you've used AppFuse 1.x, but not 2.x, you'll want to read the FAQ. Join the user mailing list if you have any questions. The Maven Reference Guide has a map of Ant » Maven commands. Maven for Newbies might also be useful if you've never used Maven before. There is some support for Ant in this release.

For more information, please see the 2.0 RC1 Release Notes. The 2.0 series of AppFuse has a minimum requirement of the following specification versions:

  • Java Servlet 2.4 and JSP 2.0 (2.1 for JSF)
  • Java 5+

Spring Web Flow 2.0 The first milestone release of Spring Web Flow 2.0 has been released.

We are pleased to announce that the first milestone of the next generation version of Spring Web Flow is now available. Spring Web Flow 2.0 M1 introduces several major new features, including support for flow-managed persistence contexts, improved support for Java Server Faces, full unified expression language (EL) support, and a more comprehensive sample web application.

I think the most interesting part of this release is Spring Faces:

Spring Web Flow 2.0 M1 introduces the Spring Faces module (spring-faces-2.0-m1.jar), a component shipped with the Web Flow distribution that contains first-class support for organizations developing web applications with Java Server Faces. The pre-existing Web Flow + JSF integration has been factored out to this project, and this project will be the home of all future JSF integration work.

The Spring Faces module provides the Spring community a dedicated project for exploring additional JSF integration opportunities. The initial work in 2.0 M1 on this front introduces integration with Ext, a popular Javascript GUI widget framework.

Of course, I also like how the new sample app looks a lot like one of Seam's demos. ;-)

JSF has needed a good client-side validation framework for quite some time. I also like the Ext integration as most JSF date pickers are hideous. Well done gents. Posted in Java at Aug 29 2007, 03:49:15 PM MDT 3 Comments
