ExpectJ Adventure

This is my script

echo "Name:"
read name
if [ "$name" == "abcd" ]; then
    echo "correct username"
    echo "Password:"
    read password
    if [ "$password" == "pwd" ]; then
        echo "Hello"
    else
        echo "Wrong password"
    fi
else
    echo "wrong username"
fi

=================================================================================

This is my Java code

import java.io.IOException;
import java.util.*;

import expectj.*;

public class Trial {
    public static void main(String[] args) {

        ExpectJ exp = new ExpectJ();
        String command = "sh /root/Desktop/hello.sh";
        Spawn s = null;
        try {           
            s = exp.spawn(command);         
            s.expect("Name:");
            s.send("abcd\n");
            System.out.println("Current status: "+s.getCurrentStandardOutContents());           
            s.expect("correct username");   
            s.expect("Password:");
            s.send("pwd\n");
            s.expect("Hello");
            System.out.println("final output: " + s.getCurrentStandardOutContents());
            System.out.println("Possible errors: " + s.getCurrentStandardErrContents());
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("ioe\n");
        } catch (TimeoutException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("toe\n");
        } finally {
            if (s != null) 
                开发者_StackOverflows.stop();           
        }       
    }
}

And this is my OUTPUT

Name:
Current status: Name:
correct username
Password:

Its not proceeding further.Its not terminating either.. I dunno why..

Does it work when you comment this line:

System.out.println("Current status: "+s.getCurrentStandardOutContents());

Maybe the application is "expecting" the value "correct username" but sees "Current status: Name:" instead (the output from your "debug" line). Not an expert on jExpert, but if the tool just redirects and monitors the System.out, it will see the script output as well as everything you print to the console.

I get it..2 consecutive s.expect() statements can never work..So to get rid of it, a \n could be added..

In this case

s.expect("correct username");
s.expect("Password:");

is bound not to work.So, it should be replaced by-

s.expect("correct username\nPassword:");//This will work
