1) i am running tomcat to host my own rss feed and this feed will get updated itself 2) i have a google reader account and subscribed to my tomcat-host rss feed 3) i have updated the tomcat-host rss feed 4) google reader does not show unread item for my tomcat-host rss feed automatically unless i refresh it manually
how to make google reader bewared of my changes in the tomcat-host rss feed automatically?
Yes. Services like that ping a number of other services for you and tell them that you have new content ready. If you'd rather ping them all individually direct from your site you can do that as well. Many blog packages will let you automatically ping a list of services when you publish new content. Does your back-end system have something like this available?

Sorry, I don't have a comprehensive list like that. However, just about every package I know from MovableType to WordPress can ping when publishing new content. Either it's a built-in function or something you can add.
I think you're misunderstanding the whole reader/aggegrator situation. A lot of these programs are offline programs. When the user turns them on they go out and scan the feeds they're subscribed to. You don't ping them, they scan your feed for updates. The frequency of the updates is dependent on the software.
You can notify multiple services of the availability of new content on your site by pinging, but that doesn't mean reader/aggregator software will automatically be updated.
