1 On the whole OSGi is overhyped thing. OSGi is a good solution to build a module system on (like Eclipse, GlassFish and WebSphere do), but it's not in itself any kind of a usable module system. It's too complicated to be exposed to the end-user and introduces as many problems as it solves.

BTW another common thing that is pitched as solving the hot deploy problem is GlassFish v3, just because they implemented session state survival after redeploy, which was present in all other containers (including Tomcat) for years.

So from the JRebelAndSeamIntegration thread: http://www.seamframework.org/Community/JRebelAndSeamIntegration, it sounds like ZeroTurnaround wants to team up with Seam to implement incremental hot deployment for EJB components.

Does Spring fwk offer similar feature?  If Seam3 has this functionality (and none others did), it would be a very good selling point to end users of the fwk...

Perhaps it will eventually make its way into the JCP as a JSR for incremental deployment of all files!

What about .NET and RoR, do they offer hot incremental deployment of all files?

Have you tried it out? What does it offer? How well does it work?
