How to get classloader for a bundle in equinox?

Question

How can I get the classloader for a osgi bundle in eclipse equinox setup. Thanks, Suraj

Answer 1

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.

Answer 2

In normal java code, you can get the class loader that loaded a given object with

object.getClass().getClassLoader();

Or even just

SomeType.class.getClassLoader();

The same applies to Equinox, just use an object or type that comes from the bundle you are interested in.
