Is there a want for a Java 7 Cloud Server Framework that is not Spring/Tomcat based?

Is there a demand out there for a small, lightweight, Java 7 based open source project that is geared toward making Cloud services more elegant? I have written several servers in my lifetime, and was curious if there was a need for this.

My thoughts were to keep it simple, lightweight, and use the Java 7 NIO 2 functionality for network communications. I was also thinking of using either a broadcast address for local cloud based communications between servers in a rack solution (MBONE) or a serialization-based communications protocol.

I don't want to use Spring or Tomcat, as they are overweight, and they are written on older Java technology. Furthermore, I don't want to use another Apache project because it's too dependent on Apache technologies. Keywords here are "small", "lightweight", "portable", and "efficient".

Maybe this will even have the potential开发者_如何学运维 of being installed and used in mobile devices as background servers, or even mobile cloud networks.

From my own point of view, no.

• If I want a lightweight servlet server, I use Jetty.
• If I want a more powerful, versatile Web app server, I use Tomcat.
• If I want a full J2EE server, I use Glassfish.

All of these are of course highly proven. Memory is cheap enough these days that I'm not very worried about a little bloat. That comes standard with Java apps :)

Also, I'd consider it crazy to deploy server technology on mobile devices. Maybe other people have bright new ideas, I think mobile devices should communicate with central servers.

I would probably not want to use a Java 7 server not based on J2EE, at least the servlet part, unless someone comes up with a really compelling alternative. On the other hand, I wonder how small you could make a compliant server.

Finally, as far as I know, Tomcat already (optionally) supports nio: http://tomcat.apache.org/tomcat-6.0-doc/aio.html .

Strictly a personal opinion from an old curmudgeon.
