JNDI Names — Is Prefix “jdbc/” needed?

Question

What's up with JNDI names? I'm trying to get a javax.sql.DataSource using the new annotations feature of Java 5. It's not working for me, so I want to ask...

I have a in my web.xml, inside of it is an element. I'm switching between "jdbc/MyDB" and "MyDB". Neither makes my class-based DataSource work (it's always null) but in another example I've created using taglibs, both of these JNDI names work.

No, it is not. It is just the convention so that it's clear to everyone what resource it is.

You can even name it k34ug6i2u3dn234uy5f, but that would lead to future maintenance problems.
