Hi :)

Look at the stack trace:

".....
Chained exception:

java.sql.SQLException: not yet implemented

at
org.firebirdsql.jdbc.FBPreparedStatement.setObject
....
"

You are calling a (in your version) not implemented method...I would say

FBPreparedStatement.setObject(int parameterIndex, Object x, int
targetSqlType, int scale).

Ciao
