access denied (java.net.SocketPermission 127.0.0.1:8080 connect,resolve)

Answer 1

I'm getting the same thing with Update 22, and not Update 21.

I'm using the TinyPlayer applet, which I'm controlling via JavaScript.

I'm loading audio files from the same domain (mydomain.example.com, IP 1.2.3.4) as the page the applet is loading on - everything is referenced using relative URLs.

When I try to play the audio, it fails to play and I get: access denied (java.net.SocketPermission 1.2.3.4:80 connect,resolve)

Looking at the access logs, I get a request for crossdomain.xml right before this happens. But the catch is that Java isn't asking for a crossdomain.xml from mydomain.example.com/crossdomain.xml ...but instead from 1.2.3.4/crossdomain.xml

The workaround that seems to work for me is to set up a virtual host that responds for the IP address 1.2.3.4, and give it a crossdomain.xml, so that Java can find the crossdomain.xml in the (wrong) place that it's looking for it.

I just tested with the contents:

...but it's probably possible to make this more restrictive.

With that in there, the audio plays correctly.
