Java Database Connectivity (JDBC)

Allthough I can acces MySQL interactively I get the following result when connecting through JDBC:

java.sql.SQLException: Cannot connect to MySQL server on localhost:3306. Is there a MySQL server running on the machine/port you are trying to connect to? (java.net.ConnectException)

Test class:
package various;

import java.sql.*;

public class Test {

private Connection con;
private Statement stmt;
private ResultSet rs;

static public void main(String[] args) {
new Test();
}

public Test() {
System.out.println("Checking MySQL access");
try {
Class.forName("org.gjt.mm.mysql.Driver");
DriverManager.setLoginTimeout(30);
con = DriverManager.getConnection("jdbc:mysql://localhost/myDb", "myUser", "myPwd");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
System.exit(0);
}

}


netstat gives:

ps -ef | grep mysqld gives:

What's wrong? In former Suse releases it worked.
