AS3 / Java - Socket Connection from live Flash to local java

I'm trying to get a live flash that lives on a webserver to talk to a local java server, that will live on the clients PC.

I'm trying to achieve this with a socket connection. (port 6000) Now, at first flash was able to connect, but it just sends <policy-file-request/>. After this nothing happens.

Now, some people at Kirupa suggested to send an cross-domain-policy xml as soon as any connection is established from the java side. http://www.kirupa.com/forum/showthread.php?t=301625

However, my java server just throws the following:

End Exception: java.net.SocketException: Software caused connection abort: recv failed

I've already sp开发者_如何学运维end a great amount of time on this subject, and was wondering if anyone here knows what to do?

---

I found the anwser, So ill post it here in case someone with a simmilar question finds this post.

The moment Flash connects to a local socket server it will send the following:

<policy-file-request/>

We will have to answer with a policy file and immediatly close the connection.
