I have successfully completed OCJP6 certification, and now planing to go for OCMJD. But don't know too much about the preparation of OCMJD, please guide me about the OCMJD and also if there is any books or study material available except oracle's own study materiel. Is it compulsory to purchase study material from the oracle for OCMJD or without purchasing the study material, I can also appear in the exam?.
