After SilverLight from Microsoft, Adobe Air got one more great competitor named JavaFX from Sun.
JavafX has variety of features as there is an option to include all Java packages or API’s in it.

      Â

The great news is there is no security sandbox in JavaFX but we can consider that too on downside because the user cannot trust the applications.

That’s not the case in Adobe Air; user can trust the applications because of the strict security sandbox.

I have been using flash for almost more than three years, I will stick to Flash.

The performance of JavaFX is greater than the AIR or Silverlight Applications I hope Adobe will take care in next versions of AIR release.

Now Adobe Air is in 1.5 and JavaFX is in 1.0 and Silverlight is in 2.0, let’s see which will be best in upcoming versions.
