The Oracle Certified Expert title, on the other hand, is reserved for specific technologies.
EJBs are a specific technology within Java EE, so the EJB certification is given the Oracle
Certified Expert title. Because this topic deals mainly with EJB technology, this is the cer-
tification we're focusing on, but there are other Oracle Certified Expert certifications avail-

Oracle Certified Expert, Java EE 6 Enterprise JavaBeans Developer exam before the Oracle
Certified Professional, Java SE 7 Programmer exam if you choose to do so. But you won't
get the EJB certification until both exams are completed. Now let's take a look at what's in
the EJB certification exam.
