Hello, everyone - I have a question that isn't strictly Java-related, but there seems to be a lot of knowledgeable people that subscribe to this mailing list. so I'm hoping someone can point me in the right direction. I know I run the risk of having several people point me in different directions, but I'm willing to take that risk (having several alternatives to choose from is way better than having no alternatives :-)). I am pretty new to web application programming in general, so I won't be surprised at all if this problem can be solved in a standard, straightforward way - I just haven't stumbled onto it yet.
I am trying to webify a legacy app and I need to solve the problem where the application may need to send unsolicited data to the "display" (which is actually represented by a browser). The problem I'm running into is that I need to push this data to the browser when it doesn't know it's coming. The best way I can think of solving this is to have an applet running in an invisible frame that opens a socket to which a servlet on the web server sends some sort of "refresh" notification when the unsolicited data is available, and then have the applet use the Java-JavaScript interface to cause the browser to ask for a refreshed web page. Are there other, better approaches? What are the gotcha's in the approach outlined above? Any help is much appreciated.
