Simple Servlet works fine with servletrunner, hangs in Netscape E nterprise Server 4.0

[Sahirad, Mohammed (London)]

All,
I have got a simpe servlet whose code is enlosed.
It runs ok in servletrunner on a Solaris box.
When you run it with NES 4.0 as the Web Server, then there are two
independent problems with it.

1-
The line
Process p = Runtime.getRunTime().exec("ls");

sends the machine CPU to near 100%. The only soultion is the brig the Web
Server down!!

2-

The servlet hangs at the line
int e = p.waitFor();
which is currently commented out.

Any help will be appreciated.

Regards,
Mo.

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class ServletExec extends HttpServlet
{
      public void doGet(HttpServletRequest req, HttpServletResponse res)
        throws ServletException, IOException
      {
         PrintWriter out = res.getWriter();

         Process p = Runtime.getRuntime().exec("ls");

         BufferedReader in = new BufferedReader(new
InputStreamReader(p.getInputStream()));

         String s = null;

         while ((s = in.readLine()) != null)
         {
            out.println(s);
         }

         boolean finished = false;

//         try
 //        {
            while (! finished)
           {
//               System.out.println("waiting");
 //              int e = p.waitFor();
  //             System.out.println("done");

               int e = 20;

               out.println("Process Returned: " + e);
               finished = true;
            }
 //        }
  //       catch (InterruptedException e)
   //      {
    //     }
      }
}
