Abstract: A method and object-oriented computing system in which a Java™ implementation of a service is provided dynamically at runtime via a Java™ interface for the service in accordance with the needs of a client computer in one of two varieties: an Enterprise Java Beans™ (EJB) implementation or, alternatively, a non-EJB implementation. Thus, the same service is accessible, without requiring any programming code changes, to both clients operating in an EJB environment and clients operating in a non-EJB environment. The client accesses the service through two non-EJB interfaces, one for the service (object or bean) itself, and the other for an abstract factory class. Both of these client interfaces are non-EJB to avoid dependence upon client access to EJB packages, which may exist for some clients and not for others.

Abstract: A method and apparatus for connecting two components is disclosed. A visual construction simplification mechanism, as part of the apparatus, is designed with intelligence that allows it to correctly configure and interconnect the two components. The invention reduces the real and visual complexity of a program by requiring only a single bootstrap connection to be established between the components. Once the initial connection is made, the visual construction simplification mechanism can make additional connections that allow the two objects two function and interoperate. Introspection is a process used to find a component's interface and identity. The visuals construction simplification mechanism looks at the interface of one component and figures out what the identity of the component is using the process of introspection. Introspection is a generic term for the ability of any component to look at the details of another component.
