What kind of service? MC currently doesn't have full OSGi service (registry) support, yet. But you can already do most of the thing you expect from OSR.

The best docs part is (unfortunately) this: - https://jira.jboss.org/jira/browse/JBCL-10 Perhaps check my demos for 'HelloWorld': - http://anonsvn.jboss.org/repos/jbossas/projects/demos/microcontainer/trunk/ Read about it here: - http://java.dzone.com/articles/a-look-inside-jboss-microconta View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4187745#...
