TangYong commented on WW-3958:
------------------------------

Now, I have tested in glassfish 3.1.2.2, and can access http://localhost:8080/osgi-2.3.1/osgi/admin/, although having a exception found in server.log.

> The OSGi plugin does not work with GlassFish where Felix is already included. When including in the Struts web application a bundle containing an activator class the following exception occurs:
> java.lang.ClassCastException: myosgi.Activator cannot be cast to org.osgi.framework.BundleActivator
> while when including a bundle with a class which implements BundleContextAware the following exception occurs:
> Exception starting filter struts2 java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/felix/framework/searchpolicy/ContentClassLoader) previously initiated loading for a different type with name "org/osgi/framework/BundleContext"
> It also seems that the plugin uses an old version of Felix which could be (at least partly) responsible for the errors since GlassFish uses a newer one.
> More details on the errors also available in [this stackoverflow post|http://stackoverflow.com/questions/14200300/using-struts2-osgi-plugin-with-glassfish]
