Java and crossdomain.xml

Does anyone have any experience with Java pulling data from another domain? Assuming my client has a minimum of 1.6.0_10, how likely is it for it to work. I've seen some posts saying it works, then others saying it doesn't, and still others saying it's broken in the later micro-updates. Any insight would be appreciated.

Thanks,

-Dan

The crossdomain.xml in 6u10 has restricted functionality. It requires a policy allowing any code from any site to connect. See the documentation for more details.

There has been at least one case where an early access release has broken crossdomain.xml, but fixed before update was completed.

Is this the documentation URL you were talking about? http://java.sun.com/javase/6/webnotes/6u10/plugin2/index.html#CROSSDOMAINXML

After reading the article it appears the crossdomain.xml file must exactly match: <cross-domain-policy> <allow-access-from domain="*" /> </cross-domain-policy>If it doesn't, then my applet won't be able to download whatever I need. As an example, the Facebook crossdomain.xml file contains: <cross-domain-policy><allow-access-from domain="*"/><site-control permitted-cross-domain-policies="master-only"/></cross-domain-policy>Which, if I understand correctly, means I will be unable to access their data from my applet.
