Hi,
I'm not sure I've understood the question - but if the question is
whether I import the package the answer is yes :)
Actually the package "Service-Found-In-SomeBundle" is exported from
someBundle.
And the pseudo code in my previous mail is actually in other bundle
which imports this package.
Well, that is probably the cause of your difficulty then. As you
probably know, uninstalling a bundle does not remove its packages,
leaving them available for existing bundles that are using them.
However, uninstalling a bundle does make the packages unavailable to
subsequently installed bundles (personally, I didn't like this clarified
R4 interpretation of how uninstalled packages are treated, but that is
the way it works now).
So, in short, when you uninstall and re-install the new version of
"someBundle", it is using its "new" version of the service package,
while your existing bundle is using the old version of the package. The
two classes are from different class loaders, thus they are not
compatible, which is why your existing bundle can not see the new service.
The simple way around this is to package your service interfaces in a
separate bundle.

Hello,
In the SIP Communicator project we were happily using oscar 2.0 for
a while but have now decided to move to Felix. We are however
running into some difficulties so I thought that someone might have
an idea what is causing them.
Here is one such Felix related problem that we didn't have with Oscar.
Bundle someBundle ......
bundleContext.getServiceReference("Service-Exported-By-someBundle");
//the service is found and working
someBundle.uninstall();
someBundle =
bundleContext.installBundle("Service-Exported-By-someBundle");
bundleContext.getServiceReference("Service-Found-In-SomeBundle");
//!!! Not found
someBundle.getRegisteredServices()
// The "Service-Exported-By-someBundle" is among the registered
services
The problem is that the bundlecontext instance we are using seems to
not be valid anymore.
Does the code above get access to the service interface of the
service provided by "someBundle"? In other words, does the bundle
containing the code above access the service using reflection or does
the bundle actually have a wire to the service interface package?
