I'll plug Apache Camel <http://camel.apache.org/> and Apache CXF < http://cxf.apache.org/> as immensely useful libraries in the OSGi world. In particular, I'd also recommend Apache Karaf <http://karaf.apache.org/> as an enterprise container for OSGi, but there's nothing wrong with embedding Felix or Equinox in an existing server (or figuring out how to leverage the existing OSGi infrastructure in your Java EE server; most if not all of them are implemented on top of OSGi nowadays including WebLogic < https://docs.oracle.com/middleware/1212/wls/WLPRG/osgi.htm#WLPRG753>).
For custom deployments, there is also Apache ACE <http://ace.apache.org/>, though I've never used it before. As for some tutorials, these guys have a bunch of sample OSGi projects using various technologies: https://github.com/cschneider https://github.com/jbonofre On 24 November 2016 at 09:12, Raymond Auge <raymond.a...@liferay.com> wrote: > Following Felix's shameless Apache/Adobe plugs ;) I'll add: > > Liferay was/is a traditionally massive enterprise WAR (but really more) > for which, in time we realized monoliths are really very #$%^&@... and so > we learned and adopted OSGi inside our application and gradually (not so > gradually actually) evolved our legacy non-modular code into our embedded > OSGi framework.
