The officials:

This certification is for Sun Certified Programmers who are already familiar with the basic structure and syntax of the Java programming language, and who have a need to demonstrate advanced proficiency in developing complex, production-level applications using Java 2 Platform, Standard Edition (J2SE) technology.

This was a great experience and i can highly recommend this certificate to any java developer. I learned a lot working on it: almost nothing new about java, but many things about design, documentation and interpretation of (intentionally) inappropriate requirement-specifications.

To cite a well-known line: "Welcome to the real world"
