Yes. com.sun.star.lang.XUnoTunnel.getSomething could almost
be your
friend (use Java serialization to transport the
java.sql.Connection
instance), but for one getSomething returns a hyper instead
of an any
(and you cannot encode arbitrary byte sequences in a hyper),
and for
another I have no idea whether java.sql.Connection is
serializable to
start with.
