I hear that the J2EE cetification includes something called the JDI? Having about a years experience, I haven't come across this term yet ..
Firstly, would anyone know what this term means, and secodnly, is there a big emphasis on it in the exam?

The Java Debug Interface is a package from Sun (com.sun.jdi) that is part of the Java Platform Debugger Architecture in J2SE. From the JavaDoc API documentation (see your J2SE's jdk directory docs/guide/jpda/jdi/index.html):
"The JavaTM Debug Interface (JDI) is a high level Java API providing information useful for debuggers and similiar systems needing access to the running state of a (usually remote) virtual machine."
However, I really think you must be thinking of the JNDI -- Java Naming and Directory Interface. I've never taken the J2EE certification exam, but I would expect that it's the JNDI that would be considered important, not the JDI.
Because J2EE is concerned with distributed objects, it must have a way to look up objects by name. JNDI is the lookup API specified for J2EE.

Thanks Gregory, and now that you mention it, JNDI is the term I was referring to . I write this J2EE cert in about 8 weeks, and although I have experience with servlets/rmi and jsps, beans and this JNDI will be new ground to cover.

Which J2EE certification are you refering to?
Is it SCWCD or enterprise architect part 1?
JNDI is one of the core components of J2EE. So, to know J2EE it is must to know JNDI.

Faisal, it's the cert for Enterprise Connectivity with Java in the Enterprise Developer track for JCert. Any suggestions for online references or simple examples?

Thanks Marcos, that's a great link. One question I have seen though is the nature of platform independence with JNDI. Is it truly platform dependant like Java is meant to be, or are there some environments in which it can't reside?
