A family of Java interfaces defines methods to provide common information about a property, such as data type and editing capabilities. The interfaces identify the methods used to get generic metadata. Implementers may extend these classes, as needed, to provide the metadata for their specific properties. The common metadata description interface of the present invention allows multiple metadata sources to be used interchangeably within the same software product without the software code being specifically written for each metadata source.

Open framework for the definition of metadata

A process and system for providing name service scoping behavior is implemented. In an object-oriented data processing system, a request is received for an initial context for a namespace from a requesting object. A scoped initial context factory object is constructed, and an initial context is requested from the scoped initial context factory object. A class for the scoped initial context factory object may be determined from a variable in a hash table object passed as an argument. In response to the request for an initial context from the scoped initial context factory object, an initial context is requested from a non-scoped initial context factory object. The scoped initial context factory object may be a subclass of the non-scoped initial context factory object. The initial context returned by the non-scoped initial context factory object is scoped to a partition of the namespace, and the scoped initial context is returned. The initial context returned by the non-scoped initial context factory object may be scoped by performing a name service lookup on the partition of the namespace. The requesting object and the scoping object may be implemented in a platform-independent object-oriented programming language, such as Java.

A computer controlled object oriented programming system for distributive program development over networks such as the internet with implement for interfacing a plurality of programming objects with each other to provide combination objects combining programming functions of said objects, each object including predetermined interface data defining a required common interface with the other programming objects as well as a framework of events and attributes and methods for manipulating the attributes. These objects may be combined with each other via their common interfaces to form combination objects, and such combination objects may in turn be further combined with other objects and combination objects to form objects of increasing complexity which function as complete programs. General purpose operations and functions are added to existent object oriented programs in an object attribute independent process. Also, this addition may be done dynamically to such existent programs. There is provided a connecting object interfacing between the original object or program being modified and a new program object which provided the upgrading operations. This connecting object includes implement for detecting the occurrence of at least one selected condition in said original object, and implement responsive to said detecting implement for notifying the new object of said occurrence. The connecting object functions independently of the attributes and methods contained in the original object.

The introspection capability of Java is utilized by the described verification tool to verify validity of a target bean's Java Archive (JAR) file. The deployment descriptor class is verified first according to Enterprise Java Bean. specification rules. The remaining classes: remote interface, home interface and bean class are all loaded into a Java Virtual Machine (JVM) and verified by the described verification tool through Java introspection.

Method and apparatus for verifying Enterprise Java Beans

The present invention provides a method and apparatus for creating objects in an object-oriented environment, such as Java. An interface is selected for and along with an implementation object. The interface and the implementation object are morphed to create a dippable object in a new class that includes the selected interface. The dippable object is able to accept new behaviors though dips. The dippable object calls an instance of the implementation object in response to calls made to the interface.
