JSF and Apache Axis at DJUG

I attended tonight's DJUG Meeting. The meeting was informative and well attended, but it was way too long. I just got home and it's a bit after 11:00. To put it in perspective, I arrived at 6:00. That's 4 1/2 hours of Java love. Elections contributed to the delay, as well as David Geary's 2 1/2 hour JSF presentation.

The basic concepts meeting covered Apache Axis, presented by Scott Davis. He showed us how easy it was to use Axis to create a web service and how to call it from the command line. The biggest highlight of his presentation (for me) was Keynote - his presentation software. It had wicked transitions and the slides looked awesome (good purchase Scott). Other cool software noted during Scott's preso was CodeTek's Virtual Desktop.

Next up was David Geary for a presentation on JSF. This guy has quite a resume: worked for Sun from 1994-97, member of the JSF and JSTL Expert Groups, author of 6 books, designed and implemented the Struts Template library (2nd committer to Struts after Craig). Books coming soon from David: Core JavaServer Faces, Core Rave, and Extreme Struts. Extreme Struts sounds very much like the Struts chapter I wrote for Pro JSP - XDoclet, StrutsTestCase, JUnit, Tiles and Validator. If you're looking for documentation on AppFuse or Struts-Resume, you'll find it in this book. If you don't remember, I wrote these apps for my chapters.

Most folks reading this blog probably know what JSF is. If you don't, it's a Java-based framework for building web applications. It is designed to replace Struts, but that probably won't happen until well after it's 1.0 release (March, Beta in December). JSF was also written to compete with .NET's WebForms, kinda like how JSP was developed to compete with ASP.

Sun's Project Rave is what supposedly will make JSF easy. Can Rave really be that much better than Eclipse or IDEA? Good luck Sun, those are two killer IDEs that are going to be very difficult to beat. And besides, has Sun ever produced any good applications? iPlanet sucks, so does Forte - comparing both to the other options out there.

I could go on and on about what I learned at this presentation, so let me just give you a brief synopsis. JSF generates JavaScript for you for event handling. The JSP tags are long and ugly, but they're named this way (i.e. <h:selectone_menu>) to distinguish a component (selectone) from a renderer (menu). David said he complained about this immensely when he joined the Expert Group, but now sees the point. No XML attributes are used in faces-config.xml - it's all entities. Reminds me of web.xml, lots of typing for not much information (what a pain - today's tool suck at deployment descriptors). JSF has no client-side validation - looks like Commons Validator will be around for quite some time. Especially since JSF requires you to specify your validation after each component in the JSP (vs. declaratively using the Validator). JSF EA4 does not work with Tiles - they're working vigorously to fix this. You can specify your navigation-rules separate from you actions in faces-config.xml (very cool feature).

If you know JSPs and Servlets, it's much easier to learn Struts (and presumably other webapp frameworks). If you know Swing, it'll be much easier to learn JSF. To me, this seems wrong. Some of the examples given tonight had HTML in .java files (for custom renderers). Are we reverting back to Servlets? Is Sun making a mistake with JSF? How is it better than WebWork or Struts? It seems to me to be an over-designed product developed by a bunch of Swing addicts.

My first impression of JSF is that it's going to be harder to teach to newbies (vs. Struts). Everyone says it's a standard so the tools vendors will come through and make it easy. The tools vendors haven't done shit for JSP and JSTL IMO, so how is JSF different? It's a good idea, it just needs to be simplified - a lot. KISS.

The first time i saw the html in the renders i also thought that it was a big mistake. But on the other hand, if you compare it to gui components, it seems logical. For example, if you want a tree, the component will create one for you. Should you really care what the html looks like? A good side effect of this is that it will force people to use css as they have no other way of modifying the look of the page (unless you subclass the renderers).
