AS7 supports OSGi bundles as deployments, and Eclipse supports the creation of OSGi bundles through the built-in PDE tooling (see [1] for an example). However, OSGi bundles developed with Eclipse PDE can't be deployed via the JBDS to AS7 yet.

Support for deploying OSGi bundles to AS7 should be added to the JBoss Tooling.
