Resending for the 3rd time, I keep getting confused with subscriptions 
and emails.

Because it is part of the J2EE specifications. The environment must be 
read-only for applications.

"Each application component defines its own set of environment entries. 
All instances of an application component within the same container 
share the same environment entries. Application component instances are 
not allowed to modify the environment at runtime."

It makes sense otherwise if you store state information in the jndi tree 
and that it is shared by all instances of the same webapp, you're just 
potentially breaking everything and security is a problem. The 
environment is supposed to be configurable by the deployer only.

See Chapter 5 (Naming) for more details.

AFAIK it is a copy of Tomcat code. Nothing else for now. And it does not 
work for remote invocation, so what would be needed is to make it 
remotable...and why not writable as it is very useful for testing purposes.
