Q. Tool which dynamically interrogates classes for their imports and generates OSGi–compliant entries.

View solution

Q. The Bundle-Activator directive describes to the OSGi environment, which class implements :-

View solution

Q. When the bundle begins to load and start, it calls the start method of the:-

View solution

Q. To start using Spring to smooth over some of the minutiae of resource acquisition and to help build more reliable systems in an OSGi environment.

View solution

Q. Spring Dynamic Modules scans our deployed bundles and loads an ApplicationContext (actually, the specific type of the ApplicationContext is OsgiBundleXmlApplicationContext) into memory based on an event, or a trigger.

View solution

Q. You’ll split your OSGi–specific Spring configuration and your plain-vanilla Spring configuration into:-

View solution

Q. To create services and have those automatically installed in the registry.

View solution

Q. Element to export the bean as an OSGi service, classified by the interface we specify.

View solution

Q. An anonymous bean specified inside of the osgi:service element allows you to avoid cluttering the namespace.

View solution

Q. The first, most direct connection to OSGi is the bean that’s created on your behalf when you export a service. This bean, an instance of:-

View solution

Q. By default, beans created in a Spring application context are global to the entire OSGi runtime.

View solution

Q. Sometimes, you may want to limit the visibility of a service so that multiple clients each get their own instance of the bean.

View solution

Q. Spring Dynamic Modules also supports injection and manipulation of bundles themselves. An injected bundle is of type:-

View solution

Q. Once acquired, the Bundle can be interrogated to introspect information about the bundle itself, including any entries, its current state.

View solution

Q. OSGi will let you maintain multiple versions of a service in your registry at the same time.

View solution

Q. Multiple services of the same interface may be registered inside of an OSGi environment, which necessitates a conflict-resolution process.

View solution

Q. When specified on a service element, allows the ascription of a rank relative to other beans with the same interface.

View solution

Q. A more robust solution to service discrimination is service attributes.

View solution

Q. There are frequently situations where OSGi will return more than one instance of a service that satisfies the interface.

View solution

Q. Attribute, which, is the symbolic name of another bundle.
