We all know that flex data services is good but is it really neccesary to implement push on flex page?? As a developer with very little money to spend on tools, I was looking out for alternatives.
And Alternative I did find!! The magic is called "XMLSocket"
Though the xmlsocket implementation is depicted as a way for the client and server to talk with xml , there is nothing potentially stopping us from sending just plain text ...
So this is how I did it..
1. Create a java based service that runs on a port (5976 in my case) that spits out content on the port when ever it is available. (This can easily be replaced by a JMS). This includes setting up a thread to write to the socket whenever data is available.
2.Open a xml socket to the server from the flash client.
3. create an ondata handler in the flex part that updates your interface .
There you have it.. :-)
I will be posting the code sample and explanation shortly .. watch out.
Happy flexing.

Hi,
I am using another free alternative, WebORB. I find it to be quite impressive. It supports messaging, streaming, remoting, etc..
In fact, I was able to make a simple instant messenger in about 15 after installation on IIS(which is also a no brainer). And since it is an AMF gateway, transfer takes place in binary format which is much faster than the XML based .NET web services I was using earlier.
Buzzy
Hi,
can you post a little example code to send xml data from actionscript xmlsocket and java socket...
the xmlsocket seems not working..
for every message, xmlsocket send a backslash zero but java can't undestand it...
thanks a lot
Lord
I dont have an example with me right now. But you have to watch out for a few things.
You have to appened a new line character after the xml string.
On the java side you have to read with readLine so a new line is neccesary
You can find a great sample here
