import java.io.IOException;
import net.sf.asterisk.manager.AuthenticationFailedException;
import net.sf.asterisk.manager.ManagerConnection;
import net.sf.asterisk.manager.ManagerConnectionFactory;
import net.sf.asterisk.manager.TimeoutException;

public class AMILogin
{
 String userName;
 String hostName;
 String passWord;
 ManagerConnection managerConnection;
 ManagerConnectionFactory factory;

 public void run() throws IOException, AuthenticationFailedException,
TimeoutException
 {
  factory =3D new ManagerConnectionFactory();
  this.managerConnection =3D factory.getManagerConnection(hostName,
userName, passWord);
  managerConnection.login();
 }
 public boolean  checkLogin()
 {
  if(managerConnection.isConnected())
   return true;
  else
   return false;
 }
 public void getCredentials(String h, String u, String p)
 {
  userName =3D u;
  hostName =3D h;
  passWord =3D p;
