Well, as you probably already know, you can become a: Sun Certified Programmer, or Sun Certified Developer, or Sun Certified Architect. IBM and a consortium of other companies are coming up with there own certification programs as well. So far they only have a program like the Sun Certified Programmer. As a matter of fact, I have been told that the SCP (Sun or IBM version) will be a prerequisite for their subsequent certifications. I have more details at work and can post them if you would like.
