Well, my efforts to get all the parts working have failed to achieve the desired results. Here's what's happening:
My Manager class gets loaded when the server starts up. It spawns a thread for each report in the database. Each thread launches an instance of the flex charting app. Now here is where is breaks down... Previously, I had the thread broadcast every few minutes the new data (these are historical charts), but since I only had one channel and channels are defined in the config files, I saw no way to couple each Thread's sendMessages to that specific instance of the flex app. So I thought I'd try Remoting. I told the flex app the reportID it was associated with and then it would call the Manager class which would look for the Thread serving that report and return the results. But the RemoteObject just creates a new instance of the Manager class each time it calls the Manager's getReportData method. So the Threads I initialized on startup never get used and the call to the RemoteObject by flex has no threads running in it, so it returns a null data set.... How do I get this working? Are channels the way to go? Remoting? Something else? --- In flexcoders@yahoogroups.com, "gjessup1" <[EMAIL PROTECTED]> wrote: > > Should work...no problem.
