Oracle, Flex and MOS - a sign for Java FX?
Ok, while we are still waiting for the Oracla/Sun purchase to go through, there is also lots of speculating about what might happen with Sun's technology portfolio moving forward.
Since the world is moving towards richer UI interfaces for the browser, I am always in the struggle to assess which technology stacks are most appropriate to learn (GWT, Flex, plain HTML + your choice of JavaScript library such as JQuery, YUI etc.). Thus, particularly as a Java developer I am of course interested in the outlook of JavaFX - I certainly "wish" it be successful, but it still seems to be lacking in various areas (Component libraries, JVM modularization, 'community'). Furthermore, there has not been any Oracles/Sun statements about the future of JavaFX as far as I know (Please comment if I am wrong)
There was a higher-level article in InfoWorld yesterday discussing the future of Sun's technologies:

Oracles involvmen into Flex
This brings me to the main trigger point that caused me to this blog entry. A few days back, I read a news article at Heise Online, a large German IT news portal, stating that Oracle has some major issues while switching over to their new support system 'My Oracle Support' (MOS):

You can read more the issues here:
I found another interesting little piece of information on stackoverflow:
http://stackoverflow.com/questions/1601444/flex-oracle-open-world-2009
According to James Ward (Flex evangelist at Adobe), Oracle showed more Flex-based applications this year at Oracle OpenWorld 2009 including: My Oracle Support, Social CRM, Siebel Gadgets and Enterprise Manager.
Can you draw any conclusions out of this regarding the future of JavaFX? Probably (hopefully) not, but it shows that Oracle has already made a significant investment into Adobe Flex.
Adobe Flex and JavaFX in Atlanta
To give you some idea of how the market looks like here in Atlanta, Ga:
At the last meeting of the Atlanta Java Users Group (November 2009), Burr Sutter our group's president asked the group (80+ attendees) whether they use Adobe Flex and a considerable amount of hands went up (I guess at least 1/3). Nobody in the rooms did anything with JavaFX...

PS: On a more frustrating side-note: While writing this blog post I visited http://www.javafx.com/ and my browsers froze (FF on Mac), causing me to re-type a good portion of my blog entry (Sigh).

Geeking out with Adobe Flex
Just some quick notes...I had some extra time this weekend and watched several excellent online presentations mostly about Adobe Flex. Adobe is doing a really good job of making their conference presentations freely available.
I worked my way through the following Adobe Max 2009 presentations:
Lastly, I ended the weekend by watching Data Visualization and Dashboards by Thomas Gonzales (from 360|Flex Conference). By the way you should also seriously check out his blog: http://www.twgonzalez.com/blog/. There is some good stuff there.
In his presentation, Thomas showed some need examples. This one causes some serious drooling: http://www.brightpointinc.com/flexdemos/googlefinance.html
And just in case you need a gauge on your dashboards: http://www.twgonzalez.com/blog/?p=34 Oh, yeah.
I worked my way through the following Adobe Max 2009 presentations:
- MAX 2009: Model-Driven Development Using Flash Builder 4 and LiveCycle Data Services ES
- MAX 2009: Photoshop CS4: The Essentials of Image Enhancement for Web and Flash Designers
- MAX 2009: What's New in Flex 4
- MAX 2009: Flash Builder 4 Advanced Tips and Tricks
- MAX 2009: Professional Flex Data Visualization: Going One Step Further

Rich Charting Options for your RIA/Webapps
I started revisiting my charting solution in jRecruiter. For this fairly basic Java web application, I have been using JFreeChart to provide basic charts (E.g. to illustrate the number of posted jobs over time).
While JFreeChart works great, and it pretty much provides all the charting features you may ever want, it has one disadvantage: It is static. Compared to all the interactive goodness that is possible with RIAs such as Flex, JFreeChart lacks the sugary icing on the top (Mouse overs, AJAX interaction, dynamic drill-down etc.). Therefore, I was investigating my options to add some richness.
Additionally, at work, I am using Google Web Toolkit (GWT) and thus wanted to get an overview about the charting capabilities I have using GWT. One of the options there is gchart. It looks okay, alas not great. What's worse, the project owner abandoned his project; see: http://code.google.com/p/gchart/.
Another option is flot which comes along as a jQuery plugin and uses the HTML canvas tag to do charting. There is a also a GWT wrapper for flot available called gflot.
The most interesting alternative for GWT, I came across is ofcgwt. It uses Open Flash Chart 2 under the hood and looks pretty good. You could argue that if you use Flash-based charting for your GWT app, why not just implement the entire app in Flex ;-).
On the pure Flash/Flex side, there are first of all the charting components that come with Flexbuilder. In contrast to the open-sourced Flex SDK, the charting components are not free, though.
While, I was googling for some other options, I saw Axiis - Simply beautiful! Yet, another option is IBM ILOG Elixir, which is free for free sites. They have a very nice compilation of examples: http://www.ilog.com/products/ilogelixir/demos/.
On a low level, you also may want to look at Degrafa (Even if it is just for the gorgeous examples). You can find one interesting charting example at this blog: Nike+ graph using Degrafa/Flex 3.
Lastly, if you don't mind spending some money, you may also look at FusionCharts. At one of my prior engagements we used used in very successfully in a Struts2-based web application. Fusion Charts also comes along in a flavor for Flex - see the samples. There is also a Google Code hosted GWT wrapper available.
This, concludes my little 30k-feet overview/list of 'Rich' charting options. If I missed a good one, please leave a comment!
