I do something similar _with_ properties configuration.  The syntax
I use is
  
  ${sessionScope.config['some.config.key']}

after doing

  session.setAttribute("config",someMap);

I'm not sure it is worth the effort to work around the "['...']"
syntax requirement/limitation, since the key/value configuration
would have to be copied into something that EL can address
directly (most simply a Map of Map [[of Map ] ...])

cheers.
