If the JavaScript support enables me to invoke a URL, it's really OK withme.


Cheers,

But a callback url is a very specific requirement. We plan to extend
javascript support to the EventListener callback.


I would say the latter is more specific than the former.

People who are comfortable writing JAVA wouldn't need any of these but the

second best thing for others would be a capability to handle it in theirown

applications. A url can be the simplest way to invoke things in respective

application. Doing it via javascript sounds like a round-about way ofdoing

it.

I can understand the concern that you do not wish to write Java code .
But a callback url is a very specific requirement. We plan to extend
javascript support to the EventListener callback . Will it help?
