hi there,
since I'm relatively new to osgi equinox so I have a question concering
bundleContext.

I'm looking out for a method within api,
which allows me to retrieve a bundleContext within a bundle
but outside the activator.

imagine following scenario:

bundle xyz.jar
- activator.java
- class1.java
- class2.java

activator implements BundleActivator,
so activator.java gets info on bundleContext via start/stop methods.

class1 and class2 should have access to a bundlecontext but without
having to implement a method to inject a context obj.

I looking out for methods like:

1. retrieve the framework singleton or get a pointer to the service registry
2. retrieve a bundle (getBundle ("<className or bundleSysmbolicId>") )
3. get the current context for this bundle

so something similar to:

Bundle bundle = Framework.getBundle(<bundleName/className>)

go on further with
bundle. ...

thanks in advance

It is usually saved statically in the Activator of your bundle.
