These involve changing which gbeans are present, not changing gbean 
attribute values.  The storage format is irrelevant to this.

I'm not sure anything except "max size" should be reconfigurable.  In 
any case, there aren't very  many parameters here and the ones you 
might change are all numbers or strings and would fit easily in a 
properties file.  Changing the security or local/xa setup should 
involve a redeploy.
