hmm, not being acquainted with the Jython and JRuby implementations
myself, maybe some comments that might help you:

    * Java programs may register "beans" which are stored in the
      BSFRegistry using a String as an index; the BSF engines usually
      supply a funtion/method to look up such beans, if you supply the
      index name (for Jython you will find BSF samples; if you can come
      up with small samples for JRuby, please consider to make them
      available, such that we can add them to the BSF samples)
          o You can look up the source of these BSF engines for Jython
            (part of the BSF distribution
            <org/apache/bsf/engines/jython>) and JRuby (should be
            available via their homepage)
    * Usually Java implemented languages have means "on board" that
      allow setting/retrieving variable values the way you are seeking.
          o Should you want to add missing functionality, then you would
            probably want to make it available via the respective BSF
            engines (at least you need to retrieve the interpreter
            instance you will be using via BSF).

HTH (and good luck!),
