Deploy Hibernate In OSGi using a features.xml file!!!

Hibernate and OSGI Implementation Made Simple Last April I kicked off FossESI to discuss how to take existing Java applications built using older technologies and implement them using new technologies like OSGi, Spring, Camel and NOSQL databases.  At the time of the kickoff, we intended to begin comparing and contrasting 3 NOSQL databases.  And just after that started, I got a real-life opportunity to help convert an existing application over to OSGi.  What I thought would be a breeze turned out to be quite an effort!  What I'll be doing over the next few months is talking about some of the lessons I learned, some of the quirks of Karaf and OSGi, and some of the tips and tricks I learned.  This week, I'll talk about how to implement Hibernate 3.3.2.GA inside of Karaf 1.6.0 without creating any new bundles!
