Just to let you know that Grizzly Deployer was adopted (almost) by another framework : Akka.
Since May 22, 2010, viktorklang is working in a branch : deployer. here the description in the commit “Starting to add Deployer [viktorklang]”
You can browse the code on github : http://github.com/jboner/akka/tree/deployer/akka-core/
I hope to see that included in a next release.
