I'm trying to use EMF in a Virgo container. In my POM I added the following dependencies:
<dependency>
<groupId>org.eclipse.emf</groupId>
<artifactId>org.eclipse.emf.ecore</artifactId>
<version>2.8.0-v20120911-0500</version>
</dependency>
<dependency>
<groupId>org.eclipse.emf</groupId>
<artifactId>org.eclipse.emf.common</artifactId>
<version>2.8.0-v20120911-0500</version>
</dependency>
<dependency>
<groupId>org.eclipse.core</groupId>
<artifactId>org.eclipse.core.runtime</artifactId>
<version>3.6.0.v20100505</version>
</dependency>
Although when I start my Server I get the following exception:
[2013-04-29 15:29:56.880] TCP Connection(6)-127.0.0.1 <DE0002E> Installation of bundle 'xxx' version '0.0.1' failed. org.eclipse.virgo.nano.deployer.api.core.DeploymentException: commit failed

And I have the feeling the Activator is trying to do something assuming an Eclipse plugin environment while there isn't one. Has anyone used EMF successfully in a Virgo bundle? Thanks!
You are right because EMF think is running in a Eclipse environment. We have integrate EMF with Virgo following the next steps:
Create an Activator class and set the registry. The code is:
@Override
public void start(BundleContext arg0) throws Exception {
Properties props = System.getProperties();
props.setProperty("org.eclipse.emf.ecore.EPackage.Registry.INSTANCE",
"org.eclipse.emf.ecore.impl.EPackageRegistryImpl");
}
@Override
public void stop(BundleContext arg0) throws Exception {
Properties props = System.getProperties();
props.remove("org.eclipse.emf.ecore.impl.EPackageRegistryImpl");
}
Finally, the MANIFEST.MF would be something like that:
Manifest-Version: 1.0
Bundle-Version: 2.7.0
Bundle-Name: EMF-Wrapper
Bundle-ManifestVersion: 2
