Well I got the select working by changing the database connect URL
from
dataSource.setDatabase
("localhost/3050:localhost:/opt/interbase/examples/employee.gdb");
to
dataSource.setDatabase
("localhost/3050:/opt/interbase/examples/employee.gdb");

I think it should have raised the error on connection rather than the
Select. I would still be ineterested to hear if anyone knows how to
fix the compile error and the 'log4j' runtime error.
