Hi, I am looking for suggestion and tips on how to push content to user.
The content I am pushing is from a real-time (yet another overloaded buzzword) source. I would like to push the data to user immediately as soon as it is available. I am integrating two systems: Jetspeed and a legacy system. At current iteration, user is expected to interact mostly with the legacy system. Ideally, performing certain actions on the legacy system would, within a reasonable amount of time, preferably immediately, cause Jetspeed to perform some action (e.g. displaying an image). The keyword is 'immediately' in the context of user interaction. So far, I have thought of the following: 1. HTML meta refresh tag. Two problems: a. At most, can only be refreshed once every second; b. It causes unnecessary network traffic and CPU load as the browser keep requesting for new page even though there is no new page available. 2. Refresh through Javascript. Same problem as the HTML meta refresh tag. 3. Maintain an open connection to the browser, pushing data as it is available to the browser. See http://www.abiglime.com/webmaster/articles/cgi/032498.htm. This is the most ideal solution for my current problem. However, I can't see a way to implement this solution within Jetspeed. Anyone know how to implement #3 within Jetspeed (or Java Servlet in general)? Is there another solution for my problem? Thank you, YS. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
