Description:

"This 5-day course introduces Java programmers to the architecture and programming of CORBA. The course consists of two modules.

The first module is designed to introduce students of various backgrounds to the Common Object Brokerage Request Architecture, or CORBA. The module begins with a short treatment of the origins and history of CORBA in the Object Management Group, and then the fundamentals of the Object Management Architecture �the infrastructure whose goals and requirements define CORBA �are covered. ORBs and Object Adapters are discussed, and one chapter is devoted entirely to Interface Definition Language: its role in the architecture, grammar, and design issues. A third chapter covers many of the most important CORBA Service specifications and prompts students to consider the architectural implications of each.

The second module gives students a solid intermediate understanding of Java Programming for CORBA �the Common Object Request Brokerage Architecture. We take a brief look at the practical relationship between the Java environment and CORBA, including how various distributed-computing Java APIs fit into a CORBA system. The Java ORB and language mapping are treated in detail. Students design and build servers, command-line and GUI-driven clients, and peer servers for a CORBA system. There is a focus on basic mechanics of distributed object interaction �using the ORB, managing object references, remote versus local access using interfaces and structs. Students will also look at thornier issues of system design and implementation with Java and CORBA, such as use of factories, naming servers, controlling location, lifecycle, and persistence.

LEARNING OBJECTIVES

· Understand the Object Management Architecture, the role of an Object Request Broker, and the assistance of the Object Adapter.

· Understand the role of Interface Definition Language in achieving interoperability between various components and design distributed systems using IDL.

· Understand the significance of CORBA Services and the implications of using or integrating various services into a distributed component design.

· Understand the relationship between the Java environment and CORBA, including the .details of the IDL-to-Java language mapping.

· Build Java/CORBA server and client applications

· Address practical distributed design issues.

Course Duration: 5 days

Prerequisites:

· Solid experience with Java programming is required.

· A firm understanding of OO concepts is strongly recommended.

System Requirements

JDK 1.2 and the JavaIDL compiler are required. Any system that supports both of these will support the lab software. A TCP network between student machines is strongly recommended but not critical.
