I have found a Bug in your newest 8.2dev-500 JDBC 3 Driver. If I create a application using Java Studio Creator 2 an run the application i get the following error:
org.apache.jasper.JasperException: java.sql.SQLException : Invalid column display size. Cannot be less than zero
With the bundeled Pointbase DB everything works fine. Older versions of the Driver are also not working. The new 500 driver is the first driver wich causes no error at design time. It would be great if you can fix this error.
My System: Postgresql 8.0.1 Windows XP Professional SP2
