[jcifs] Exception when accessing Smb files from an applet which has been Reloaded

[Florian.Jirschik at Linde-LE.com]

Dear All,

maybe you can help me with this issue. I've got an Java Applet which
connects to a SMB ressource to list a shared directory's content.
It is run in the Sun Applet Viewer. If I start the applet for the first
time or restart it (a menu entry within the Applet Viewer), everything
works fine.

But if I reload the applet, the SMB connection fails with this error
message after a timeout of 30000 ms:

jcifs.smb.SmbException:
jcifs.util.transport.TransportException:

I've tried it using JCIFS 1.2.16, 1.2.14, 1.1.11 and JRE 1.5.08, JRE 1.3.x.
It's all the same, the error message is a little different with JCIFS 1.11.
Thats my applet code:


import jcifs.smb.NtlmPasswordAuthentication;
import jcifs.smb.SmbFile;
import jcifs.smb.SmbFileInputStream;
import jcifs.smb.SmbFileOutputStream;
import java.awt.*;
import java.util.Date;

public class LiFilepoolTestApplet  extends java.applet.Applet {

      public void start() {
            Date d1 = new Date();
            try {
                  NtlmPasswordAuthentication ntlm;
                  ntlm = new NtlmPasswordAuthentication( "domain", "name",
"pwd" );
                  SmbFile dst = new SmbFile( "smb://servername/share/",
ntlm );
                  SmbFile[] sfArr = dst.listFiles();
            } catch(Exception e) {
                  e.printStackTrace();
            }
            Date d2 = new Date();
            System.out.println("time: " + (d2.getTime() - d1.getTime()));
            repaint();
      }

      public void paint(Graphics g) {
      }
}


Any help would be appreciated.
