Right, but look at http://mina.apache.org/sshd/
The second sentence of the web site is:
"SSHD does not really aim at being a replacement for the SSH
client or SSH server from Unix operating systems, but rather provides
support for Java based applications requiring SSH support."
That said, I agree we could provide a simple CommandFactory that would
just run the underlying OS command out of the box.
Maybe try something like:
sshd.setCommandFactory(new ScpCommandFactory(new CommandFactory() {
public Command createCommand(String command) {
return new ProcessShellFactory(command.split(" ")).create();
}
}));
