Come on, the net is loaded with matches for such an error..

If you don't already know google (you should, it's great), here's

That means that your JDBC driver was compiled for JRE 1.5, and your JRE
is older than that.

Run "java -version" to see your JDK version, and download the
appropriate JDBC driver. See
http://jdbc.postgresql.org/download.html#jdbcselection for a list of
compatible JDK and driver versions.

Or you can upgrade your JDK to 1.5 or newer.

Hi Doron,

you need the PostgreSQL driver version suitable for your JRE.
At http://jdbc.postgresql.org/download.html you can determine which
driver-jar you should select.

Regards,
Martin
