I'm interested in the OSGi Enterprise specification. At the moment I'm only interested in the JDBC connectivity, but that may change.
At http://www.osgi.org/Download/Release4V42 I can find the osgi.enterprise.jar (the companion code link). Can I just install it in my equinox container and use it?
I had the impression that some of the classes are overlapping (for instance org.osgi.service.component), doesn't this lead to problems? Or should I then just uninstall the org.eclipse.osgi.services bundle and use the osgi.enterprise instead?
No. You can't do that. The file from OSGI.org is mostly interfaces, it is not complete implementation.
