Spring ORM Bundle - ClassNotFoundException [message #835286]

Hi all! Im have a library that uses the javax.persistence.metamodel.Metamodel class sometimes.

This library is a normal bundle, importing the javax.persistence.metamodel package, and this import is resolved normally. But when I try to library, this exception occours:

Caused by: org.eclipse.virgo.kernel.osgi.framework.ExtendedClassNotFoundException: javax.persistence.metamodel.Metamodel in KernelBundleClassLoader: [bundle=org.spring
framework.orm_3.0.5.RELEASE]

I see that the Manifest on org.springframework.orm-3.0.5.RELEASE bundle is missing this package import (but all other javax.persistence imports of the 2.0 spec is present). So, after add the package import with optional resolution, as the others, the application works well.

This can be a bug on the manifest header of this Virgo provided bundle?

Im using Virgo 3.0.2Release.

The org.springframework.orm-3.0.5.RELEASE bundle is provided by the Spring framework project. Perhaps you would like to contact that project to see whether this is a bug. Meanwhile, please note that you can add an import without editing the bundle by attaching a fragment, which is probably a more maintainable workaround. See this FAQ.

Hi Glyn! Thanks by help. I will create a fragment bundle to import this package. I need to configure this bundle inside any existing plan, or it will be activated together with Spring ORM Bundle if I put it on the Virgo repository?

I will post this question on Spring too.
