Summary, review and resources for further study

CORBA Programming with Java is a lab-intensive course intended to get the student thoroughly used to writing CORBA applications. The course includes a series of lab exercises that build upon each other to result in a comprehensive applications. The labs constitute around 50% of the course duration. The course includes a discussion of the latest features in CORBA, and a review of the upcoming CORBA standard.
