Re: Exception on call to isValid() method

OK, found the JDBC4 driver. Now I get,

org.postgresql.util.PSQLException: Method org.postgresql.jdbc4.Jdbc4Connection.isValid(int) is not yet implemented.
at org.postgresql.Driver.notImplemented(Driver.java:728)
at org.postgresql.jdbc4.AbstractJdbc4Connection.isValid(AbstractJdbc4Connection.java:53)
at org.postgresql.jdbc4.Jdbc4Connection.isValid(Jdbc4Connection.java:21)

isValid() is an abstract method. So, am I to assume that the driver itself does not have isValid() implemented?

OK, thanks. I will look for a JDBC4 driver...

isValid is a JDBC4 method and you have a JDBC3 driver.
