RE: why My main thread exit when IOStreamConnectorThread exits?

Are you sure that your program reaches Here 

"                    //wait untill the command is executed and read the 
			   result from the file 

                     cmdd ="exit\n";
                     out.write(cmdd.getBytes());"

Hi have a problem very similar, I´ve to load the environmental variables defined by the user shell so, I do a startShell() then execute the command env like you execute the command above., I can get the command result but the next command ( exit ) do not run.

What are you doing in "//wait untill the command is executed and read the" ?

Thanksx

Subject: [Sshtools-users] why My main thread exit when IOStreamConnectorThread exits?

Hi,

I have started using SSHTools in my application one month ago. My 
application should  connect and  run commands on the remote server 
regularly. In my main application I have loop and in this loop I will run 
the commands on the remote server. My problem is that after the first use 
of  openSessionChannel() , startshell() and finally exiting the usershell, 
my main thread also seems to exit.

Here is an example of my code:

public class myclass()
{

   static SshClient ssh=null;
   static SessionChannelClient shell_session=null;

   //it is a swing application
   public myclass()
  {
   //initialize my frame and panel ...

  }

   public static void main(String[] args)
   {
      //initialize the ssh with password authentication

     myclass my=new myclass();

     while(true)
         {
                System.out.println("reached here");  //only printed once!! 
I do not know why??

                  shell_session = ssh.openSessionChannel();

              if (!shell_session.requestPseudoTerminal("vt100", 80, 24, 0, 
0, ""))
          		{  System.out.println("Failed to allocate a pseudo terminal");
             	   shell_session.close();
                         throw(new Exception());
                    }

             if (shell_session.startShell())
              {
                      IOStreamConnector output,error;

                       output =    new IOStreamConnector();
                       error  =    new IOStreamConnector();

                    myStdOutPrintStream = new PrintStream(
                                                           new 
BufferedOutputStream(
                                                                        new 
FileOutputStream(new File("c:\\myoutput.txt")) ));

                      output.connect(shell_session.getInputStream(), 
myStdOutPrintStream);
                      error.connect(shell_session.getStderrInputStream(), 
System.out);

                    OutputStream out = shell_session.getOutputStream();

                    String cmdd="runblast" + "\n";
                    out.write(cmdd.getBytes());

                    //wait untill the command is executed and read the 
result from the file

                     cmdd ="exit\n";
                     out.write(cmdd.getBytes());

                      shell_session.getState().waitForState(ChannelState.CHANNEL_CLOSED); 


                    output=error=null;
                    shell_session.close();
                    shell_session=null;
	} //if


           }//while

     } //main
} //myclass

  after the "INFO: IOStreamConnectorThread is exiting" in log , the 
"reached here" message is not displayed anymore. It seems like as if my 
main thread exited with IoStreamConnector!!

I appreciate if you can help me.

Thanks for your time and have a great day.

Mahshid
