Hi there,
we want to use EMF in a plain OSGi application, where even equinox might
be replaced by some other OSGi kernel (e.g. felix).
By "use" I mean that we want to use the generated classes and saving and
loading of resources.
I understand the main requirements for EMF are
* org.eclipse.emf.ecore
* org.eclipse.emf.common
* org.eclipse.emf.ecore.xmi if you want XMI support
In a plain Java application it is sufficient to put those jar files into
the classpath.
However, in our OSGi context, EMF is also dependent on
org.eclipse.runtine and this pulls in a whole bunch of Eclipse specific
plugins, which we don't want to have, i.e.
* org.eclipse.core.contenttype
* org.eclipse.core.jobs
* org.eclipse.core.runtime
* org.eclipse.equinox.app
* org.eclipse.equinox.common
* org.eclipse.equinox.preferences
* org.eclipse.equinox.registry
Any way to use "plain EMF" in an OSGi context?
As a workaround I could create a new bundle and put the three core EMF
bundles into this plain bundle. Sounds like a bad hack.
Any other best practices?
Cheers,
Hauke

Hauke,
You can look at https://bugs.eclipse.org/bugs/show_bug.cgi?id=328227 for
some details. Repackaging is the simplest approach...
