Hi,
I want to create web application with real-time updated charts.
So client specifies parameters and continuously receives some
some data. As it's possible to have different clients with different
parameters - server-side I will do in beans with session scope.
Please, advise the way/technology to implement this.
I think this may help // Get the keys for maximum values of page views and visits
function max_key($array) {
foreach ($array as $key => $val) {
if ($val == max($array)) return $key;
}
}
$array = $pviews;
$precord = max_key($array);
$array = $visits;
$vrecord = max_key($array);
// Always use max. value recorded in array for y-axis
$ymax = 1*(max($pviews));
// Devide it by six and round up to nearest whole number to set appropriate y-axis ticks
$ytick = ceil((max($pviews))/6);.
I'd have a look at how facebook realizes the chat and news stream functionality. You can see some rather interesting AJAX calls in Firebug (Firefox Debugging Plugin). It has a Javascript Function which polls an AJAX backend on regular basis. It further adjusts the repolling frequency based on factors - which aren't disclosed I assume - but user interaction intensity would be one I'd consider for reducing the amount of update calls.
Existing continuous integration systems are generally built around one of two disparate architectures, and generally implement only a subset of desirable features. As CI systems mature and their user populations grow, we would expect them to grow additional features; however, implementation of these features may be constrained by the base choice of architecture. It will be interesting to see how the field evolves.

methods a client wishes to execute in a server. It is _very_ easy to use
and is implemented for lots of languages, including Java. Using XML-RPC
your clients may be written in Java, Python, Perl, C++, PHP, ASP and so
on. It doesn't matter who generated the call, it's all XML anyway.
