I am working on primefaces datatable which has data from the database. This client side data is received when the refresh button is hit. If there is a database change, the client doesn't know about it and has to refresh the page often.

I was looking for server side push technology and getting to know about WebSocket. However, I cant find or do not know how it will work in my situation. The database change is done through Hibernate. So how do I monitor the database change done by hibernate? and, after detection send that value to the client? I am using Java and tomcat.

since you're using primefaces, you can use the p:poll widget to monitor the server side.

OR

you could leverage the primefaces support for atmosphere.

if you're just monitoring a small amount of changes, a poller would probably be the easier solution. if you need to provide reactivity to a large number of changes, the pf-push and atmosphere framework will give you a good base to leverage.
