About Question enthuware.oce-ejbd.v6.2.539 :

Post by deadlock_gr »

The second answer (marked as wrong) says:
It allows an enterprise bean to modify its environment properties without knowing about them at the development time.
The explanation says:
This is wrong because a bean cannot change its environment. It gets whatever the assembler/Deployer gives to it.
Although I agree the answer is wrong, I think that the explanation is wrong. The bean can change its environment overriding what the assembler / deployer have set by using InitialContext.rebind().
Is this correct or not?

A container is only obligated to provide a read only namespace. Context.rebind() is not guaranteed to work.

Can someone please elaborate on option 4. What does it mean "locate external information without prior knowledge of how the information is named and organized" ?

It basically means that you do not need to hardcode the names in your code. A bean can look up information from the JNDI namespace dynamically. The data in the JNDI itself can be changed by external systems.

In the explanation, what does ISV stands for? I could not find it from the spec.
