Yes, that makes a bit more sense. In that case a java applet would probably be the most sensible alternative to Flash. My guess is that if someone's browser permits neither Java nor Flash you're not going to have a lot of luck with any other alternative either, so having both a java and flash option for the comms proxy should cover you pretty well. The flash one will load a lot faster and as mentioned before will be easier to write, so I'd still suggest having it there as an option. It would also allow you to have the rest of the system working when you write the applet. That way you can narrow down the possible causes of problems to the applet itself. > >>So it might be possible to do something like this ... >> >>1, Instantiate the java chat server from CF - maybe even have >a CF GUI >>for an admin or two. >> > >Translates as: >There will be a need to instantiate the Java chat server once. >The ColdFusion generated HTML would probably have controls >that could start/stop the chat server - and as you say to find >out how many clients are connected. Yes, The simplest implementation of this is to use CFEXECUTE to run a batch file that starts or stops the chat server. Once the server is up and running you'd need to have some way of talking to the server from CF. Off the top of my head I'd say the most likely implementation would be to write a class that CF can instantiate. That class would have public methods that CF could call to connect to the server and issue commands. > > >Hope this clears things up a bit and thanks again, Yep, that's clearer now.
