How to get classloader for a bundle in equinox?

Question

I have read a lot of equinox code for this, but still can't figure out a non-hacky way of getting the classloader for a osgi bundle in eclipse equinox setup. Is there one?

Answer 1

In OSGi 4.3 you can use:

bundle.adapt(BundleWiring.class).getClassLoader()

Answer 2

The short answer (certainly for OSGi 4.1, not sure of 4.2) is you can't get a bundle's classloader. However the Bundle interface exposes a loadClass() method and this would allow you to write a classloader that wraps the bundle API and delegates to that loadClass() method. Or you can save some time and use Spring DM's BundleDelegatingClassLoader class instead.
