I have a JEE App with EJB and Webservices that call a business level application (BLA) that expose OSGI Services through SCA.

I want to deploy my JEE App on a vertical and horizontal (4 servers, 2 nodes, 2 machines) cluster in WAS.

It is possible to deploy my BLA on the Cluster?
If I need to update an OSGI Service on the internal repository I can modify it on one of the two nodes?
So the question is: OSGI repository is Clusterizable or my bundles have to be deployed alway on all the WAS cluster nodes/servers/OSGIRepositories?

thanks Diego
