Is there a way for a class to find out the name of the bundle that is
contained in, or alternately to get the Bundle object itself? I see how to
do that if the class is derived from WorkbenchPart, but what about classes
that are not part of any specific class hierarchy?
Thanks,

Sunil,
I'm hoping to avoid having to put the bundle name into the code or into a
properties file or something. In other words: starting with no Bundle
object and no bundle name, can a class find out what bundle it is part of?

Starting with no Bundle object?
Why would you want to do that?
And "Bundle-Name" is not the actual bundle name, but the name of the
manifest attribute which points to the bundle name.

ServiceReference ref =
context.getServiceReference(PackageAdmin.class.getName());
if (ref != null) {
PackageAdmin admin = (PackageAdmin)context.getService(ref);
Bundle bundle = admin.getBundle(object.getClass());
bundle.getSymbolicName() -> voila...
}

Which works fine unless you've created a plugin from an existing Jar file,
in which case there is no BundleActivator class in the plugin.
But I've worked out another way to solve the problem that I thought I
needed a bundle for, so thanks to you and to Sunil for your input.
