CORBA Junction: IDL for CORBA 3.0
The Object Management Group's Interface Definition Language has always enabled developers to create object relationships based on inheritance. When working with complex designs, however, we often need to support objects that contain multiple interfaces and are constructed through composition rather than through inheritance. This week, Dave Bartlett explains how the CORBA Component Model fulfills this need, by extending the Component Implementation Definition Language and standardizing the way component interfaces are defined.

Java Tip 73: Test your Java/CORBA server from the inside
Testing a server class can be difficult. A test sequence written as a client program may have only limited access to the features of the server class.

Add the power of CORBA to our distributed whiteboard
Our last tango with our shared whiteboard app illustrated how to use servlets to implement a communications layer.

Applied CORBA: Integrating legacy code with the Web
Developing Web-based applications using CORBA provides a number of advantages over the other distributed object technologies (RMI and DCOM).

JDBC via CORBA
Some people are trying to get JDBC to go through CORBA and ultimately over IIOP. After harping about how this will inherently be slow, I decided to post instructions on how to this, so people would spend little time discovering how bad it was. However, when I worked on the demonstration, it turned out to be reasonably fast at least for a single user going over IIOP between two NT hosts on an Ethernet LAN.

Java Tip 65: Measure data transfer speeds via Sun's ORB in JDK 1.2 beta 4
In this brief tip, you'll get a simple Java benchmark for data transfer speeds using CORBA. Source code is provided, which means you can modify the program. The benchmark consists of client and server applications that use Sun Microsystems's Naming Service

Locating CORBA objects using Java IDL
Implementing CORBA objects is no trivial matter. In fact, it's a feat worthy of a round of high fives. Once the celebration subsides and everyone has left your cube suitably impressed with your coding talents, you must figure out how to publish your new object so that any computer on the enterprise can easily locate it. What else would you use but a naming service?

Servlet Inter-communication with CORBA
This article gives a brief overview of CORBA, then discusses servlets and demonstrates how servlets can communicate with CORBA servers. The example in this article use JavaIDL and Tomcat. If you want to see how a CORBA client can be implemented as a stand-alone application or as an applet, see Getting Started with JavaIDL.
