EMF Plug-in question [message #517073]

Hello,

I have a plug-in that is using EMF. The problem I am having is that the plug-in is not getting activated. We are using JWS to deploy the application. I was checking the details info button in the Help menu and I notice the following:

org.eclipse.emf.common (2.4.0.v200902171115) "EMF Common" [Installed]
org.eclipse.emf.ecore (2.4.2.v200902171115) "EMF Ecore" [Installed]
org.eclipse.emf.ecore.xmi (2.4.1.v200902171115) "EMF XML/XMI Persistence" [Installed]

Can someone tell me what [Installed] means? Shouldn't it be [Active] like the others in the list?

Jerome,

Plugins are generated activated upon first use. All the EMF plugins
have a MANIFEST.MF that contains

Bundle-ActivationPolicy: lazy

Of course there are reasons a plugin might fail to activate, such as if
the version range dependencies it has aren't satisfied, e.g., EMF 2.5
won't run on Eclipse 3.4. If you run with the -debug (and maybe the
-clean) flags, Eclipse will produce more detailed diagnostics to
describe why things aren't being activated.
