SpringSource has just launched a new application server, called SpringSource Application Platform, that is based on Equinox, Tomcat and Spring. The key thing is that it is not a Java EE application server but one that has been designed for modular development and deployment.
InfoQ has a good write-up about the announcement and Dana Blankenhorn has provided some coverage. It will be interesting to see how this announcement is received in the Java community. The Spring guys have a great reputation and community, so it will definitely get attention.
Of course this is great news for Equinox and OSGi; lots of innovation coming for this platform.
