             Summary: Support OSGi Containers
                 Key: ISIS-1301
                 URL: https://issues.apache.org/jira/browse/ISIS-1301
             Project: Isis
          Issue Type: Wish
          Components: Core
            Reporter: Jörg Rade
            Assignee: Dan Haywood
            Priority: Minor


Currently the war artifact contains all jars the application depends on.

* Repackeging these unchanged jars over and over takes some time (in my case this is at par with compiling dom). 
* The footprint of the war when redeploying it over thin connections requires more bandwidth. 
* Supporting OSGi containers would have the addional benefit that only changed artifacts would have to exchanged in the running container. Production systems could benefit from the possibility of the OSGi lifecycle, ie. replacing artifacts without downtime.

This will involve multiple steps, eg.

* Using more bundled versions of dependencies (where available - Wicket, DataNucleus, Jetty already are bundled)
* Building a bundled war (wab)
* Making isis libs conform to OSGi's class loader requirements
* Bridging the OSGi ServiceRegistry to use its Servies as DomainServices
