Hi all! I am almost done studying for the exam and now i am on EJB environment. The concept of JNDI context is apparently a fundamental one, and it's critically important to know precisely what it is. I am yet to see a clear, meaningful and full explanation of what a JNDI context is. Can you guys help me out, please, and give me a good explanation of what a JNDI contect really is. This would solve many of my confusions about the EJB environment. thanks much

A JNDI context is a "place" where "things" can be looked up. That's it. In fact, you don't really get tested on the ins and outs of JNDI. All you really need to know is how to lookup homes, when you need to narrow them, and the semantics of resource refs of different types. JNDI is pretty simple at its heart--its just how you use it that is confusing sometimes.
 
It is sorta covered in the JavaRanch Style Guide.
