I have two unrelated questiojns.
  1.  What is I/O restricted in a container?  Since I'd have the chance to close
files on passivate or store and open them on activateor load, how does file I/O
differ from an entity bean or session bean talking directly to a data store?
For example, my impression is that you could make an entity bean that makes to a
non-relational data store,like SAP records.  Why is taht okay to do, with
specialized ejbLoad and ejbStore metods, but it is ot okay to simply open and
close a file?

  Is there any way to inherit from an EJB?  It would be nice, having made a
generic class, to be able to subclass it for special purposes, but I see no way
to do this.  Is it possible?  DO I need special container-based tools to support
it?  Thanks.
