Describes CORBA Portable Interceptors, which are objects that an ORB invokes in the path of an operation invocation to monitor or modify the behavior of the invocation transparently.

This column is the first in a series that focuses on the CORBA Component Model (CCM). It first outlines the evolution of programming abstractions from subroutines to modules, objects, and components. Then it describes how this evolution has largely be...

Explains the Dynamic Any, which is the standard facility for manipulating values of constructed types within Dynamic CORBA applications.

Takes a look at the relationship between XML and CORBA and explores the topic of versioning.

Takes a look at how to extend the functionality of an open-source program without actually changing the source code.

Compares SOAP and IIOP and then concludes that Web services and CORBA are not rivals, but instead are complementary.

Describes how middleware is evolving to support distributed real-time and embedded systems. Focuses on real-time CORBA.

Presents the CORBA DSI (Dynamic Skeleton Interface), which is the server-side counterpart of the CORBA Dynamic Invocation Interface.

Discusses various alternatives of passing XML-defined data between client and server. Concludes with a brief discussion of SOAP and Web Services and how they relate to CORBA.

Shows how CORBA developers can use the IFR (Interface Repository) to construct truly dynamic applications that discover all necessary type information at run time.
