[Wrapper-user] getting thread dump

[Giovanni R. <g.r...@so...>]

dear Leif,

I think I wasn't able to clearly explain my problem that I described in =
my previous post (error loading Wrapper.dll)

the problem (and the question) is the following:

how can I get a thread dump of my java application if it has been =
installed as NT Service and has been started from Control Panel - =
Administration tools - Services ?

thanks for your help

best regards

Giovanni

  dear experts,

  I would like to get a thread dump of my app via telnet.

  This is the code:

  package it.soltec.test;

  import java.io.IOException;
  import java.util.Date;
  import java.util.Timer;
  import java.util.TimerTask;
  import org.tanukisoftware.wrapper.WrapperActionServer;

  public class TestWrapper {

      private Timer timer =3D new Timer();
      private MyTimer myTimer =3D new MyTimer();
      private String library =3D "java.library.path";
      private String wrapperDllPath =3D =
"D:\\j2sdk1.4.2\\tools\\wrapper_win32_3.0.5\\lib";

      public TestWrapper() {
          int port =3D9999;
          WrapperActionServer server =3D new WrapperActionServer( port =
);=20
          server.enableShutdownAction( true );
          server.enableHaltExpectedAction( true );
          server.enableRestartAction( true );
          server.enableThreadDumpAction( true );
          server.enableHaltUnexpectedAction( true );
          server.enableAccessViolationAction( true );
          String property =3D =
System.getProperty(library)+";"+wrapperDllPath;
          System.setProperty(library,property);
          System.out.println(System.getProperty(library));
          try {
              server.start();
              System.out.println("Server running on port "+port);
          } catch (IOException e) {
              e.printStackTrace();
          }
          timer.schedule(myTimer, 0, 5000);
      }

      private class MyTimer extends TimerTask {
          public void run() {
              System.out.println("time: "+new Date());
          }
      }

      public static void main(String[] args) {
          new TestWrapper();
      }
  }

  When I try to connect via telnet I get the following error:
