just for completeness, there's also: Apache Felix Dependency Manager (uses a builder-style API) http://felix.apache.org/site/apache-felix-dependency-manager.html Service Activator Toolkit (tooling is primarily Eclipse based) http://www.kevindog.com/sat/help/topic/org.eclipse.soda.sat.plugin.doc/books/book.html peaberry (Guice extension, can also work with non-OSGi service registries) http://code.google.com/p/peaberry/ so there's quite a choice out there, and all of them can co-operate via the service registry :) I will take a look at the DS and iPOJO stuff.
