sshd sshServer command no output to client

[Mark Robinson <ma...@fulgentcorp.com>]

Hi,
I am new to SSHD. I have tried to follow the documentation and tips on the SSHD web site to create a simple sshServer.
At this point it receives the command from the SSH client but no output is returned from the command (e.g., the directory contents when sending "ls -l" as the command).

Here is my server code:

import java.io.IOException;

import org.apache.sshd.SshServer;
import org.apache.sshd.server.Command;
import org.apache.sshd.server.CommandFactory;
import org.apache.sshd.server.command.ScpCommandFactory;
import org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider;
import org.apache.sshd.server.shell.ProcessShellFactory;

public class CopyOfServerTest {

	public CopyOfServerTest() {
		// TODO Auto-generated constructor stub
	}

	public static void main(String[] args) {
		SshServer sshd = SshServer.setUpDefaultServer();
		sshd.setPasswordAuthenticator(new NoPasswordAuthenticator());
		//sshd.setPublickeyAuthenticator(new MyPublickeyAuthenticator());
		sshd.setPort(12250);
		sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider("/pathto/hostkey.ser"));
		sshd.setShellFactory(new ProcessShellFactory(new String[] { "/bin/bash", "-i", "-l" }));
		sshd.setCommandFactory(new ScpCommandFactory(new CommandFactory() {
		    public Command createCommand(String command) {
		    	System.out.println("******** COMMAND is " + command);
		        return new ProcessShellFactory(command.split(" ")).create();
		    }
		}));
		try {
			sshd.start();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

Console output is:
