Can I instantiate a class inside a bundle?

["Ivo K. Koga" <iv...@gmail.com>]

Hi all,

I'm trying to instantiate a class from one bundle inside another. Can I do
it? Maybe exporting from one and import from another. Is that the point?

Well, you can do Bundle.loadClass() on the bundle from which you wish to 
load the class and then just do Class.newInstance() on it. However, 
unless you have imported the class, then you will not be able to cast to 
the class directly and will have to use reflection.

If you import the class' package from the bundle, then there is nothing 
special you need to do, just the normal "new MyClass"...

Yes, you can do that by exporting and importing it.

Alternatively, you might want to consider using a factory pattern  
here (for example a service that creates the instance for you). Of  
course this depends on your exact use case (which I know nothing of,  
so this is just a shot in the dark :) ).
