Hello all,
I'm trying to use a Java program to check if the Karaf SSH client that comes
with the program is working. For this I wrote a simple Java program, but the
client does not return the result. When I run the command "bash -c
./bin/client -u karaf -p karaf \"system:version\"" manually in the console it
works, but not when I run it through the program.
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class App {
public static void main(String[] args) throws Exception {
System.out.println("SSH Client Check");
testSSHClient();
}
public static void testSSHClient() throws Exception {
String commandUnix = "bash -c ./bin/client -u karaf -p karaf
\"system:version\"";
String clientLoginResult = executeSSHClient(commandUnix);
System.out.println(clientLoginResult);
}
private static String executeSSHClient(String command)
throws IOException, InterruptedException {
StringBuffer output = new StringBuffer();
Process p = Runtime.getRuntime().exec(command);
p.waitFor();
BufferedReader reader = new BufferedReader(new
InputStreamReader(p.getInputStream()));
String line = "";
while ((line = reader.readLine()) != null) {
output.append(line + "\n");
}
String result = output.toString();
return result.trim();
}
}
Does anyone have any idea what could be the reason for this?
Regards
Alex
