[flexcoders] Flex 2B2: Cross-platform bug in XMLSocket?

[Tobias Patton]

Hello flexcoders (and Adobe, I hope);   I’ve been working on getting a Flex application to talk to an application on the local machine through an XML socket. Getting this to work using the Windows Flash player was trivially easy. Getting it to work using the Mac OS X Flash player has so far proven impossible.   I’m using the SimpleServer Java code shown at: http://livedocs.macromedia.com/labs/1/flex20beta2/00002515.html   The client code is very simple. It basically calls socket.connect( “localhost”, 8080) and socket.send(…). I will paste it into the email below my signature.   For these initial tests, the client is running from the local filesystem and the server is hosted on the same machine.   When running using the Mac Flash Player, the socket is never connected on the client side. However, as soon a the client calls m_socket.connect(…), the server’s call to socket.accept() returns. So the server thinks the socket is connected, but the client does not. When I kill the client by closing the browser window, the server echoes the text “<server-policy-request/>” to the console which means that this text was received on the incoming socket.   The security policy request is strange, in that when both client and server are running on the local file system under Windows, no such request is made. However, I think it’s tangential to the main problem – it does not seem possible to connect a socket when running under the OS X Flash Player.   I would be very gratefull is someone could look at my code and tell me that I’ve made a stupid mistake.   Thanks. Tobias.
