I have a rss feed, I am able to connect the RSS feed using java using
apache.commons.digester API
Is there any API in java to listen to that rss feed (as an when it is updated) ?]

I don't think you are able to get push notifications from RSS. A work-around would be to add a "listener" that polls the feed at a high frequency, and pushes the information to your application only when it detects a change. But this is just masking the polling that you are already doing.

I am not aware of the exact solution you are looking for.

I am not doing any polling. I want to listen to the .rss url.

Right now i am just using HttpURLConnection to call the abc.xyz.rss url and get the data.
something like
URL url=new URL(abc.xyz.rss);
HttpURLConnection httpSource=(HttpURLConnection)url.openConnection();
Channel channel=(Channel)digester.parse(httpSource.getInputStream());
Item rssItems[]=channel.findItems(); //this contains items from rss
     
I want to listen to abc.xyz.rss  as and when abc.xyz.rss  is updated which is the requirment in our project


thanks
