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
