Well, this would be a feature of the BSF engine for your language
(accessing, changing, storing Java objects in the BSF registry).Depending on the scripting language at hand making BSF registry entries available transparently to your programming language as if they were variables defined in the context of your script code could be easy/simple (e.g. because it already supports Java bindings one way or the other) or complicated (has no clues of Java at all, hence the bridging/interfacing support needs to be created).
