The essential function of JDBC is to connect to the database and send SQL statements to the server. When requests come in from a remote platform a communication factor is introduced. We've used the type 4 drivers with UNIX and linux and AIX for several years now very successfully. Whenever the actual code encounters any type of error, it throws an exception, which then goes to the call stack.
Most development efforts are now focused on adding new features, improved memory management, and stability in the new JDBC Universal Driver.Table 4.
