Here’s a simple tip for all of you AJAX lovers using JSF 2.0. It is possible to render components that live outside of the form where your AJAX tag lives; actually, it’s possible to render any component by using it’s fully-qualified component ID.

Just prefix the target ID with the naming-container separator character, usually “:”, and provide the full name of the component as it is rendered on the HTML page.

<f:ajax execute="validatePasswords password @this" render=":messages" />

It is amazing what can be done in exactly one year’s time.  January 17th will have been the 2nd anniversary since Lincoln Baxter and I started OcpSoft.  It’s been one seriously fun, and wild, ride with JavaServer Faces and the open-source community.  I want to take a moment to talk about my partner’s success story and what he has accomplished in just one short year.

As a vocal blogger, I feel responsible for promoting and sharing the good work of others, whether that be technology, creative work, or in this case: a book. I will take no exception to that philosophy when it comes to the JavaServer Faces framework. For a quick read, try the summary. If you are intrigued, read on! I hope you find this review valuable.

It was about one year prior to this article that I wrote “JSF2 is in good hands”, in which I spoke about the upcoming release of JavaServer™ Faces 2, and how the community had changed immensely in the few years I’d been using the tool. There were changes I wanted to make, and started making them by publishing an open source extension called PrettyFaces.

PrettyFaces lets you map Pretty URLs to any resource within a JSF-based web-application (eg: /example -> /faces/examples/page.xhtml). While this is stuff that other web-frameworks have been doing for years, (WordPress, Rails/Grails, etc) it’s stuff that has traditionally been hard using JavaServer Faces – until around November 2008, when the first release was published.

Now, I’m relatively new to this arena – I entered the open source community for the first time about four years ago, working on PHP and Perl modules. I’ve been using it, and appreciating it, for almost my entire life in the industry, but never giving back. I suppose one question that many people ask is, “Will working on open source software get me anywhere in my career?”

As a member of the JSF 2 expert group, I’ve stated that my primary goal is to make JSF, and J2EE, more accessible to the community at large, to reach out and make sure that people’s voices are heard, and that what we are doing makes sense. I’ve only been part of the group for a little under a year, but I’ve met some pretty cool people, and you’d be surprised at how interested they all are to hear your story.

Here’s an email from David Geary (a long-time EG member) to the Expert Group, that I think paints a very nice picture of people’s reaction to JSF and JSF2, author of Core Java Server Faces (Core JSF):

JSF2 is an amazing web-framework, and as part of our initiative to engage the community, Dan Allen, Andy Schwartz, Kito Mann, the rest of the Expert Group, and I have been putting together a “JSF Root Node” (as Ed Burns put it.) A website to be the first place people go to when they think of JSF.
