Clean way to stop a Bundle from inside
Hi,
I would like to know what is the proper way to stop a bundle from inside the
code?
I implemented bundle having a controller which listens to a service A.
I would like to stop the bundle from inside when the service A leaves.
I want to have the bundle in a resolved state so I can start it later from
another bundle
I tried two ways:
1-
public void stop(BundleContext context) throws Exception {
serviceRegistration.unregister();
context.removeServiceListener(this);}
But then when I list the bundle list ("ps"), the bundle is still in an
Active State and not Resolved
2-
public void stop(BundleContext context) throws Exception {
this.Ctxt.getBundle().stop(); }
But then when I list the bundle list ("ps"), the bundle is in an resolved
State but I have the following trace of exception
*ERROR: Error stopping bundle. (org.osgi.framework.BundleException: Bundle
auto.generated.sendps [48] cannot be stopped since it is already stopping.)
org.osgi.framework.BundleException: Bundle auto.generated.sendps [48] cannot
be stopped since it is already stopping.

I'm not sure what you are trying to achieve, but you cannot stop a
bundle from its BundleActivator.stop() method, since that method is only
called when the bundle is being stopped.
Having a bundle stop itself is generally not a good idea and is a little
tricky. I think Peter Kriens did a blog on this, which gives you some
pointers (e.g., use a separate thread, etc.), so look for it.
