CORBA and Java Compared: Object Model

: This paper compares Java and CORBA object models. By identifying main characteristics, the paper highlights similarities and differences of both models. Moreover, the key concepts of both object models are overviewed, including object definition, operations, requests, types, interfaces, classes, meta-classes, and inspection. A brief comparison of both models is presented at the end of the paper. 2 This paper has been written as an attempt to map and compare features and capabilities of two distributed object systems that seem to attract more and more interest these days --- Java and CORBA. Each system is represented by its object model that defines what is the notion of object for this system, how the system treats objects in terms of lifetime, operation invocation, mutual communication, etc. Object models are distinguished based on the number of types for which a given operation can be defined. Classical object models require operations to be defined on a single type. If a model..
