| [equinox-dev] Bundle classes context problem |
|
Hi, I have a bundle called ClassManager which get the
classes which are being installed in the framework and print their names. The problem is that these classes are the name of another services
classes which have been registered in Equinox after my bundle ClassManager was
installed, so when a new bundle is installed, a method in ClassManager is called
which is the next one: getMethodFromClass (String class_name) { Class myclass = Class.forName (class_name); } Where class_name is the name of my new Service which has
just been installed. The problem is that my bundle throws a
ClassNotFoundException because of class_name (which is the name of the Service.class
that was registered) is not in the ClassContext for ClassManager, and it is
normal, because ClassManager is a system bundle which can not know the name of
the classes which will be registered in Equinox. I though it could be because of security permissions but I
have tried launching Equinox without security and I got the same Exception: The full Exception is shown below: java.lang.ClassNotFoundException:

class which are exported in a package in the classpath of OSGI so that other
bundles can use them? Thank you in advance |
