I'm willing to explore knoledge in Business Component.since i didnt appear for (SCJP)Prerequisites elgibilty to do SCBCD, i've found SCEA can be appearable without any Prerequisites .Even though SCEA has 3 steps, it 'll take me as higher leve in my career .
It seems like you already know what you want, don't you?
SCEA certification [still] looks impressive to those management types, so go ahead and to it. On the other hand, SCEA part I contains ~30% questions about EJBs, so if you did SCBCD you can easily try SCEA part I as well. For both SCJP and SCBCD there are good books available, so if you got 3 years experience, it's about 3 days of preparation for each exam.
