New release of JSF AJAX Components (Updated)

Many thanks to my pal Vernon Singleton for handholding me through the process of converting these huge QuickTime files down to much smaller FLV and SWF files. Maybe he'll do a blog on how to do it!

Nearly a year ago, the BluePrints and JSF teams at Sun began to work on the story of how AJAX and JSF would work together. As we began to get into it, we found that these two technologies were very complimentary. We developed and continue to refine techniques for how to use AJAX with JSF.

The landing page for the Java BluePrints AJAX components is: <https://blueprints.dev.java.net/ajaxcomponents.html>

I've recorded a screencast blog for each of the components in the catalog. Please excuse my slow pace of speaking, I'm aware that we have a large contingent of European JSF developers and my tendency is to speak fast American English. Therefore, I made a conscious effort to speak slowly.

• Introduction

• AJAX Autocomplete Text Field

• Google and Yahoo Map Mashup Component

• AJAX Live Progressbar Component

• PayPal "Buy it now" Component

• AJAX Netflix style "rating" Component

• Live Progressbar enabled AJAX Fileupload Component

• AJAX Popupbaloon Component

• AJAX Dynamic Text Label Component

• AJAX Validator Wrapper Component

These components leverage the Dojo Toolkit and make use of the JSF PhaseListener approach for serving up JavaScript files and handling AJAX requests on the JSF server. This approach was innovated by the Blueprints and JSF teams and generalized in the Shale Remoting library, which these components leverage to great effect.

Comments

• Wow, these components look awesome. Is it possible to build and deploy without Glassfish? In just plain Tomcat 5.5?

• Yes you can deploy them on other app servers and web containers as well as GlassFish. There are 2 component libraries, one of them is based on JSF 1.1 and the second library is based on JSF 1.2. As long as the app server or web container supports the proper version of JSF, then the components should run fine. The list of components in each library is at

• Thanks for the response Sean. Two questions I still have tho. 1) Can you build without Glassfish? If so, how? The ant build.xml seems to expect it to be installed and have the build.properties file modified to point to the install. 2) What makes a web container support JSF? As far as I know, the only thing that really matters is what version of the jvm your running and the Servlet/JSP version the web container supports, right?

• How appropriate it was Dojo. Definitely one of the stronger js api designs out there.

• He Ed.
  Are you aware that the autocompletion only seems to work if you browser runs with en-gb as language?
  Try set you browser language to Danish, and the static/META-INF/common/script.js
  will say
  java.lang.IllegalArgumentException: Invalid date format: ma, 24 apr 2006 07:44:45 GMT

  Just for you info, and thanks for a great component.

• brunatager -- Please take a look at the Eba JSF Ajax auto-complete combo box. I have ensure this is fully i18n. My demo works with strings such as "Østfold", part of norway.

• Ed do any of these samples allow the Ajax request to save data?

• Hey checkout my new screencase:

• Hi, I had some problems with several of the attributes for the progress bar. I needed to add some code to ProgressBarRenderer.java to write out the javascript function pointers correctly. I'm not sure if there's a newer version that has these changes, but I thought i'd post them in case there wasn't.

  For each of the javascript "on" calls, a new Function has to be added, eg:

  if (onComplete != null && onComplete.length() > 0) {
  writer.write("bpui.progressbar.state[\""); //NOI18N
  writer.write(clientId);
  writer.write("\"].onComplete = "); //NOI18N
  writer.write(" new Function(\""); // CRW 20061106
  writer.writeText(onComplete, "onComplete"); //NOI18N
  writer.write("\");"); // CRW 20061106
  writer.write("\n"); //NOI18N
  }
  Note the changes that I've made by my initials.
  The same exact changes must also be made for OnFail, OnUpdate, etc, which I will not post since they need the same changes.

• Didn't realize i had to post in Html

  if (onComplete != null && onComplete.length() > 0) {

  writer.write("bpui.progressbar.state[\""); //NOI18N

  writer.write(clientId);

  writer.write("\"].onComplete = "); //NOI18N

  writer.write(" new Function(\""); // CRW 20061106

  writer.writeText(onComplete, "onComplete"); //NOI18N

  writer.write("\");"); // CRW 20061106

  writer.write("\n"); //NOI18N

  }

• This is awesome stuff, Ed.

  I am wondering about the increased complexity of using AJAX + JSF in a large scale dev project and its impact on timelines, developer productivity, cost etc...

  Anyone care to comment?
