JDBC and Applet on Linux-Apache - Mailing list pgsql-interfaces

Hi everybody, 
I`ve a problem with an applet that simply connect itself to a postgres DB
and receive the result of a SQL query.\\
Applet on Netscape give me the error:

java.sql.SQLException: No suitable driver

catched for the code Class.forName("postgresql.Driver")

The incredible thing is that an application with the same code run
correctly on the same machine!!
Have anybody some suggestion?

Thanks for the time,
Filippo

Follow the code...
P.S.
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
//import postgresql.Driver.*;
