Welcome to the Javaranch forum!
First of all you should consider taking SCJP exam in order to go ahead and take more complicated examinations, like SCJD, SCWCD, SCBCD etc.
With best regards,
I've already passed SCJP and recently SCJD (both java 5 edition).
Returnin to my question - is is worth to certify in EJB if it's not so popular as Spring (I'm assuming that in some way these technologies are interchangeable to some degree)
It is definitely worth to go for the EJB certification. As you know EJB is a standard specification. If Spring weren't a lightweight container, no one would have cared about it. I would from my personal opinion say that it is really worth to give the SCBCD certification.

Did a rm -R / to find out that I lost my entire Linux installation!
I have also made the same question on the form because i felt that Spring framework is more popular than EJB3.0 in industry.
But as i started EJB3.0 in action, I realized EJB3.0 is standard technology accepted by big app server vendor names likes IBM, Oracle.
EJB3.0 will be industry accepted technology very soon. and here on important point from EJB3 in action.
"As we mentioned earlier, EJB-3.0 and Spring are often seen as competitors; however,
if you look more closely, you can see that they can also be complementary."
