There are two cases where a location is bound 'dynamically'. 1) A bundle calls ConfigurationAdmin.getConfiguration(pidX) and a new configuration is created (i.e. no existing configuration exists). In this case it gets dynamically bound to the calling bundle. 2) A configuration exists with pidX with a null location. A) a bundle calls ConfigurationAdmin.getConfiguration(pidX), calling bundle gets bound or B) a ManagedService is registered with pidX, the registering bundle gets bound.
The only way to have a 'statically' bound configuration is when a management agent uses ConfigurationAdmin.getConfiguration(pidX, location) where location != null. All other situations will be dynamically bound and should result in the configuration getting unbound when the bound bundle is uninstalled. To me that makes the most sense and is the most simple explanation.

Thus one might argue, this results in a static binding to the caller's bundle. On the other hand, one might argue, that this binding is dynamically set upon the first time it is used by a bundle. > > What is the correct answer in Situation B ? Static or Dynamic ? Location binding only applies when a configuration object is *created* in response to someone calling getConfiguration (or getFactoryConfiguration), so in B: - the first all makes it dynamic - the second call binds it to the consumer At least, that's my interpretation. :) Greetings, Marcel _______________________________________________ OSGi Developer Mail List [email protected] https://mail.osgi.org/mailman/listinfo/osgi-dev
