Research from Sun's website

The main page for the certification is here (German).

To achieve the SCJD certification, one needs to complete a programming assignment, and write an essay which serves to prove that the finished program was not written by someone else. The exam exists in only one form, i.e. there are no variants for J2SE 5 and J2SE 6.

The certification code for the programming assignment is CX-310-252A. The code for the exam is CX-310-027.
