Exception in readLine() for DataInputStream for netware 6.5

Question

Hi,
In netware 6.5 with Service pack 4, I want to read the environment variables set.
My code is
import java.util.*;
import java.io.*;
import java.lang.System.*;
class InsTest {
public static void main(String [] args) throws Exception {
String cmd[] = {"envset"};
InputStream is = (Runtime.getRuntime().exec(cmd[0]).getInputStream());
DataInputStream ds = new DataInputStream (is);
System.out.println(ds.readLine());
This code is throwing an java.io.IOException that Bad File Number.
How it fix this exception ?
With Regards,
Vara Prasad.
