cannot find symbol

[Ericyue]

hi ,

i writing a program to let it print screen and send to others pc , below is my code :

import java.io.*;
import java.util.*;
import java.lang.*;
import java.lang.*;
import java.awt.Toolkit;
import java.util.Timer;
import java.util.TimerTask;
import java.awt.image.BufferedImage;
import java.awt.Rectangle;
import java.awt.Dimension;
import java.awt.Robot;
import java.io.File;
import javax.imageio.ImageIO;

public class testRSH implements Runnable
{
private StreamHandlers streamHandlers = new StreamHandlers();

public testRSH(){}

Toolkit toolkit;
Timer timer;
public void run()
{

class RemindTask extends TimerTask {

public void run() {

try {
Toolkit tool = Toolkit.getDefaultToolkit();

Dimension d = tool.getScreenSize();
Rectangle rect = new Rectangle(1024,768);
Robot robot = new Robot();
Thread.sleep(1000);


File f = new File("screenshot.jpg");
BufferedImage img = robot.createScreenCapture(rect);
ImageIO.write(img,"jpeg",f);


} catch(Exception e){}




}//close public void run
}//close class Reminder

};

public void test()
{
try
{
//Function call to capture the screen
run();

//Function call to set the RSH execution command
executionCommand = sshFileRSH("192.168.1.104", "pc2", "screenshot.jpg ", "/home/pc2/Desktop", "/home/pc3/Desktop");

//Run teh RSH command
Process p1 = Runtime.getRuntime().exec(executionCommand);
InputStreamReader isr = new InputStreamReader(p1.getInputStream());
streamHandlers.checkStreamOutput("From RuntimeExecution", isr);

}
catch(Exception e)
{
System.out.println("Error in RuntimeExecution: " + e);
}
}

//Function to set the RSH SCP command
private String sshFileRSH(String hostName, String userName, String localFileNames, String remoteDirName, String localJobDirectory)
{
String fileTransferCommand = "scp " + localFileNames;
//String fileTransferCommand = "rsync --partial --progress --rsh=ssh " + localFileNames[0] + " " + localFileNames[1] + " " + localFileNames[2];

String destinationCommand = userName + "@" + hostName + ":" + remoteDirName;

String executionCommand = "";
executionCommand = fileTransferCommand + " " + destinationCommand;

return executionCommand;
}
}

when i try to compile , i get a error as below:

testRSH.java:60: cannot find symbol
symbol : variable executionCommand
location: class testRSH
executionCommand = sshFileRSH("192.168.1.104", "pc2", "screenshot.jpg ", "/home/pc2/Desktop", "/home/pc3/Desktop");
^
testRSH.java:63: cannot find symbol
symbol : variable executionCommand
location: class testRSH
Process p1 = Runtime.getRuntime().exec(executionCommand);
^
2 errors
