Guess what ;-)
<vendor>
JBoss has a JNDI implementation, and a java:comp/env usage of it, that
can be used in all of the above cases, easily.
All you need to do is add the implementation JAR, and a small piece of
init code to set up the context switching semantics of the "comp/env"
JNDI context. This piece of code is, of course, available as an MBean in
JBoss.
It works by having the "env" context be switched on what Thread
ContextClassLoader is set for a particular thread. The number of virtual
"env" environments you have is thus dependent on how many classloaders
you use TCCL's. Each TCCL will have its own "env". (see
Thread.setContextClassLoader(ClassLoader) for details on TCCL's)
