The code is available via subversion at sourceforge.net.
Source only. The jotscale is checked out as an eclipse project from http://jotscale.svn.sourceforge.net/viewvc/jotscale/trunk/jotscale/ or the equivalent svn path. (see source forge). It's not for the light of heart, but I'm working on it..
The checkout is an eclipse project and happens seamlessly except that JotScale now depends upon Mojasi which is available from the same svn as jotscale but at trunk/mojasi
Just check them both out and you are up and running. I think my email here is broken, so contact me via source forge.

2) I have written an asynchronous http server. It has been proven up to 50,000 clients per server. I have a new model for web services that is very 'ruby like' while still being written in Java and not requiring Erlang. (see demo.jotscale.com). We can support uploading of class files describing web services into a running system, and also 'agents' to do map-reduce type of distributed processing.
-----------------------------------------
JotScale is all about making it easy to write realtime interactive web applications that scale endlessly and painlessly. Potential applications range from realtime web events with 100,000 or more participants, to massively multiplayer games, to realtime auctions, to social websites where participants may have thousands or tens of thousands of watchers, all of whom are expecting realtime updates.
JotScale doesn’t require contortions to handle growth but just the simple addition of commodity servers. JotScale doesn’t require months of preparation for disaster recovery but instead needs nothing more than additional sites with more commodity servers.






JotScale is Open Source. We firmly believe that any code that's used to build a web business needs the Open Source advantage. Given time, publicly-reviewed code is just flat-out better. And we hope people will join us in improving the code to make it an even better foundation.
