I can't connect to DB

[Ekrem Altintas]

Hi there,
I,m trying to connecting to sample database of NetBeans 6. But I'm getting an error on this line:

Class.forName("org.apache.derby.jdbc.ClientDriver").newInstance();

It says:

Method "forName" in class "java.lang.Class" threw an exception: instance of java.lang.ClassNotFoundException(id=349)

How can I solve this problem?

Thank you

        Connection conn = null;        
        try
        {
        
               String userName = "app";
               String password = "app";
               String url = "jdbc :mrgreen: erby://localhost:1527/sample";
               Class.forName("org.apache.derby.jdbc.ClientDriver").newInstance();
               conn = DriverManager.getConnection (url, userName, password);      
 
        
        }
        catch(Exception e)
        {
            System.out.println("Error!!!");
        }
        
 
              
    }  
}

Make sure your driver is in your classpath.
