Does anybody know how to use Java to write a live update web page? just like those live score updates from those sports web pages. 'coz I know servlet can only pull information from server, so how can I push those info. from server out to the web-based client? Thanks in advance.
You have to use java to keep the information updated in the server. But you don't need to use it to update the client, you can just make the client to request the info periodically. You can get this with a HTML meta tag: <meta http-equiv="REFRESH" content="60">
