java + sftp

[Bumsys]

I execute the program:

public class SshExample {

/**
* @param args
*/

public static void main(String[] args) {
// TODO Auto-generated method stub
SshClient ssh = new SshClient();

try {
String hostname = "localhost";
System.out.print("Host to connect: " + hostname);
ssh.connect(hostname);
// ssh.connect("localhost", new
ConsoleKnownHostsKeyVerification());

PasswordAuthenticationClient pwd = new
PasswordAuthenticationClient();

String username = "anabolik";
System.out.print("Username: " + username);
pwd.setUsername(username);

String password = "111";
System.out.print("Password: " + password);
pwd.setPassword(password);

int result = ssh.authenticate(pwd);

if(result==AuthenticationProtocolState.FAILED)
System.out.println("The authentication failed");

if(result==AuthenticationProtocolState.PARTIAL)
System.out.println("The authentication succeeded but
another"
+ "authentication is required");

if(result==AuthenticationProtocolState.COMPLETE)
System.out.println("The authentication is complete");




SftpClient sftp = ssh.openSftpClient();

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

When the execute the line SftpClient sftp = ssh.openSftpClient(); I
have error:

What can do?

 

[dontlikenicknames]

First of all, is the authentication succeeding? What is this block
printing out?

if(result==AuthenticationProtocolState.FAILED)
System.out.println("The authentication failed");

if(result==AuthenticationProtocolState.PARTIAL)
System.out.println("The authentication succeeded but
another"
+ "authentication is required");

if(result==AuthenticationProtocolState.COMPLETE)
System.out.println("The authentication is complete");
