Unfortunately, the Java code I worked on is proprietary, so I can't provide any examples. It was also over a year ago, so my memory cache has been flushed.<shrug/>
The basic approach I used was: * open a connection to the server * receive a stream of 'update event' strings * parse strings to determine what to update and to which value * queue the updates Then, in an UpdateManager thread, I would apply a set of updates to the DOM. I defined the update event string format to be something easily parsable. I basically needed an element id, a new value, and it seems that I needed an alarm flag which was used to flash some elements. There are a number of other approaches, but this was enough to do what I needed. Hope that helps, G.
