The java code is reasonably agnostic, provided the JDBC driver is smart
enough to
deal with any datatype properly as strings, although that intelligence
can be added.
Something else as a slave would be considerable easier, of course. For
something
else to be the master, you would have to find a way to mimic the
trigger code to make
the entry into the _rserve_log_?_ tables.
