Consume XML Push Data Feed on Open Channel with Java

I am looking for some example Java code and/or utility library for consuming an XML push data feed over http.

I already know how to consume and parse a basic XML feed using XStream and STax. That is - I can send an XML request over http, get an xml response back and process it.

However, I have an option to subscribe to a data feed. The connection is kept open and the server pushes any new data onto the channel. I then need to process any data as it becomes available.

I can probably figure it out on my own, but it is always better to see some examples. I thought that this kind of data-feed-subscription would be fairly common. But I can't seem to find any examples. Maybe I am just searching on the wrong key words?

I would appreciate it if anyone knows of a Java framework/utility and/or example code for consuming a push xml data feed over http.

    HTTP push isn't really quite defined term and there are several ways to do it. Best approach is to use appropriate client (be it comet, web-sockets, HTTP streaming or whatever) and see what kind of interface it provides. There will probably be an easy way of connecting you existing XML parser to it.
