I can't connect

Hi,

I installed debian 2.2r2 with _all_ the postgres-packages, I created a database and via psql I can do whatever I want with the DB. Now I'm trying to make a connection via a Java-program. I downloaded the jdbc-6.5-1.2.jar file and renamed it to jdbc.jar and moved it to ~/jdk1.3/lib, set the CLASSPATH to ~/jdk1.3/lib and used a program, found in the Deitel&Deitel Java book.
After that, I tried to make a connection to the database I created (testing) and I keep getting error-messages.

Can someone help me with this? I'm trying for 3 days now and still no luck.

Thanks,
Bart

public class TableDisplay extends JFrame
{
private Connection connection;
private JTable table;

public TableDisplay()
{
String url = "jdbc:odbc:testing"; // I also tried with <String url = "jdbc:postgres:testing";>
String username = "postgres";
String password = "notentered";

try
{
Class.forName("jdbc.Driver");
connection = DriverManager.getConnection(url, username, password);
}
catch (ClassNotFoundException cnfex)
{
System.err.println("Failed to load the JDBC/ODBC driver.");
cnfex.printStackTrace();
System.exit(1);
}
catch (SQLException sqlex)
{
System.err.println("Unable to connect to database.");
sqlex.printStackTrace();
}
