the OCMJEA exam is homologous with the old Sun SCEA ?
Err... Your English is better than mine, but for example, I took SCEA part I in 2010 and OCMJEA part II and III in 2012, and there was no problem, though I did have to take a hands-on course. My assignment was graded in three weeks (and I passed :-) ).
The content of the exam is the same, so yes, the same books apply.
Cheers-
