Info

A URL classloader is used to load classes in the mediator (class mediators are not deployed as OSGi bundles). Therefore, it is only possible to refer to the class mediator from artifacts packed in the same CAR file in which the class mediator is packed. Accessing the class mediator from an artifact packed in another CAR file is not possible. However, it is possible to refer to the class mediator from a sequence packed in the same CAR file and call that sequence from any other artifact packed in other CAR files.
