Aah, okay. That's the same thing as <env-entry> in web.xml, I think.

That looks good.

Right. Since you are getting those values from JNDI, you can simply
replace them in JNDI. Instead of using envCtx.lookup(varName), use
envCtx.bind(varName, newValue) to change it.
Instance preference change.
A JNDI browser might simplify this for you if you can either deploy it
into your existing application, or if you can somehow connect to it from
the outside. Otherwise, you can write some quickie preference editor
yourself.
