The OS which i use is Windows NT

My Directory structure is as follows

root
-----pack1
-----pack2

i added the following in the classpath

d:\root\pack1;d:\root\pack2

i compiled superclass in pack1 (package 1 direcotory) w/o errors

But when i compile subclass or (derived class) i
get the following errors :-

derived.java:3: Package pack1 not found in import.
import pack1.*;
^
derived.java:5: Superclass root.superclass of class pack2.derived not found.
class derived extends root.superclass
^
2 errors

i compile this file being in directory pack2.

Source code for both the files r as follows :

SUPERCLASS
package pack1;

public class superclass
{
protected int i=10;

public superclass(){}

public void display()
{
System.out.println("Superclass Display called !!! ");
}
}

Source code for DERIVED class is as follows

package pack2;

import pack1.*;

class derived extends root.superclass
{

public derived(){}

public static void main(String args[])
{
derived obj = new derived();
obj.display();

}
}

ClassPath which i have set is as follows

.;C:\jdk1.2.2\bin;C:\jdk1.2.2\lib;D:\Blazix\blazix.jar;.;C:\jsdk1.1\lib;c:\jsdk1.1\src;d:\.;d:\root\pack1;d:\root\pack2
