Is there a good, maintained solution for Server Push with Google Web Toolkit?

Question

The GWT RPC mechanism is great for client initiated communication. We're looking for a solid, supported way to do Push notifications from the server to the clients. All the solutions we can find are several years old and don't seem to work with newer versions of Eclipse and GWT.

We're prepared to use the Google App Engine if that helps.

We can roll our own socket code if that helps, as well, but we are Java developers. Writing JavaScript to do socket work would be a last resort, although if that's what it takes and there are examples we could probably handle it.

Any pointers to sample code or suggestions as to packages to use are greatly appreciated.

Answer 1

You could use the Atmosphere Framework. They have a gwt20 module which works great with gwt.
