Can't load Postgresql JDBC driver

I am using Enydra5.0 and Postgresql 7.3 on Linux. I got the latest JDBC 
driver, file is pg73jdbc3.jar and is located on /usr/local/pgsql/lib.
My classpath have also been set to point to the JDBC driver and exported.

While starting up the server using the "run" script, I encounter the 
following error:
