Loading class from extension point [message #1107507]

Hi all,

We have an extension point which specifies class name as one of its attribute. We need to obtain the class instance from the provided class name String.

So far we only find IConfigurationElement#createExecutableExtension, but this one creates object instance instead of class instance. Actually we need something like Bundle#loadClass, but how to get reference to Bundle from IExtensionRegistry ?

Any help would be greatly appreciated.

Thanks & Regards,

Setya

Hi all,

I've found the following works:

Bundle bundle = OSGIUtils.getDefault().getBundle(element.getContributor().getName());
Class<?> clazz = bundle.loadClass(className);

But the thing is OSGIUtils is internal, so I'm open for any suggestions.

Thanks & Regards,

Setya

Use Platform.getBundle instead:
