Re: Extending the GWT Tutorial App StockWatcher

My understanding is that http://en.wikipedia.org/wiki/WebSocket is the coming "standard" way to do things like this. Stills seems quite a wild west part of web technology. 20 years of the client just pulling from the server...

Thanks for the link, I'll check it out.   This is part of a leaning process to control a couple of physical devices externally "attached" to the host computer.

It would be unusual to start a thread on the server to do this.

Why don't you want the client to poll?

If you really want to push from the server then you are into complicated stuff like https://code.google.com/p/gwt-comet/   I've never used any of this stuff.

What is your server implemented in? In JEE starting your own thread is against the spec. There are things like scheduled jobs etc to do that for you.

Deep waters if you really are a novice! 

All the best

I just completed the GWT tutorial StockWatcher on my Ubuntu 12.04 machine using the IDE Eclipse. 

The second part of the tutorial implements an asynchronous call back but what I want to do is move the timer to the server side to make it completely asynchronous. But I don't quite see the way to do this.

Will I need to start a thread on the server side for the timer?. I'm pretty much a novice at web pages, css, and servers.
