I liked the part where it suggested a JS JVM was useful since JS could be compiled for the JVM.

It is only a matter of time until somebody gets a webbrowser running inside another with javascript as a joke.

What will be interesting is to see how long we have to wait afterwards until someone decides that it might be a useful thing to do in production.

I know you're kidding, but I'd love to play with a sandboxed browser-in-a-browser.

Get a performant IE6 running inside Chrome, and I'd pay good money for that.

Various people from Opera Software mentioned that their company had plans to do this in case of success and possible monopoly of Chrome OS.

It is only a matter of time until somebody gets a webbrowser running inside another with javascript as a joke.

And just a bit longer until someone has it running inside Minecraft

Ample SDK does that, kinda-sorta -- http://www.amplesdk.com/about/compatibility/

Does this mean it might be possible to run java in the browser with out it grinding your computer to a halt?

I don't know, but if a JavaScript VM will succeed where native Java Applets/JavaFX failed, someone at Sun will not be getting a bonus that year.

dotBen• 14 years ago

hate to break it to you, but Sun hasn't existed as a company since early 2010...

I doubt it, straight Java is much faster than converting Java to Javascript and then executing it, even with JIT.

lucian1900• 14 years ago

Actually, if Doppio generated JS instead of interpreting JVM bytecode, it could be quite fast.

kumarm• 14 years ago

In current form no (Looking at demo and quick snap shot of whats in there) but might happen in future.

minimax• 14 years ago

I don't see anything like a Java compiler in the Doppio source.

edit: I get it. In the demo they are using a Java compiler from Sun that is itself a Java program running in the Doppio JVM. Neat.

devongovett• 14 years ago

Check out the demo. It definitely contains javac http://int3.github.com/doppio/

What a wonderful world, on one end you have people moving client side code to the server (node.js, Dart, Meteor) on the other hand you have people trying to move it to the client (GWT, Doppio)

jebblue2• 14 years ago

I'm thinking the client people have the edge. If you're running a web site, why pay for a big machine when you can let each client use their own.

lmm• 14 years ago

Because the alternative is writing javascript shudder.

jebblue2• 14 years ago

This is so cool how can you not like the concept. I even tried "globalthermonuclearwar" but it just wanted to play Tic Tac Toe. :-)

I guess the letter campaign was the slower path to getting Java on iOS.
