Declarative federation of registries

A registry helper that facilitates declarative federation of registries, comprising:

• a processor;
• and
• a memory coupled to the processor and storing modules that when executed by the processor provide functionality, the modules comprising:
• a reader module configured to read a declarative description for a target registry to obtain parameters pertaining to mirroring of the target registry in a federated registry;
• a listener registering module configured to register a listener for the target registry that enables external monitoring of the target registry based on the declarative description parameters;
• a change detecting module configured to detect a modification to the target registry via the listener;
• and
• an updating module configured to update the federated registry in accordance with the detected modification to the target registry, wherein the updated federated registry mirrors the services of the target registry.

A computer-implemented method for facilitating declarative federation of registries, comprising:

• a processor;
• and
• a computer readable medium coupled to the processor;
• reading a declarative Extensible Markup Language file for an internal registry that is stored in a Java Archive file to obtain parameters pertaining to mirroring of the internal registry in a federated registry;
• registering by the processor a listener for the internal registry that enables external monitoring of the internal registry based on one or more declarative description parameters that indicate the name of a method that should be called on a Java-implemented registry listener class in order to register the listener on the internal registry;
• detecting by the processor a modification to the internal registry via detection of an event by the registered listener;
• and
• updating by the processor the federated registry in accordance with the detected modification to the internal registry, wherein the updated federated registry mirrors the services of the internal registry.
