I'm planning to build an example showing both BlazeDS and Comet integration of an OpenLaszlo app with a Scala/Lift backend. Scala implemented the Erlang specific Actor based approach for concurrency, reducing the complexity of handling threads drastically.<div><br></div><div>- Raju</div><div><br><div><div>On Aug 20, 2009, at 2:33 PM, Sebastian Wagner wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">I will have to think about a solution that gets into my project earlier.<br>I thought it would easiest to integrate into javaRPC.
