Shouldn't that just be catch (const MysqlPackage::Mysql::MysqlException
& ex)

Is your client calling an idl method that is declared to throw this
exception?

At the risk of my talking nonsense, I don't think that's correct.

If you add "new", then you are throwing a pointer to the exception. For
one thing, you could then have to catch a pointer as well (rather than
catching by value or by reference), but I don't believe that the CORBA
C++ mapping tells you to throw pointers - you are just supposed to throw
the object. So if you _did_ throw a pointer, then omniORB wouldn't
recognise it, and you'd just end up with a generic exception at the
client.
