[JSch-users] java.security.NoSuchAlgorithmException: DH KeyPairGenerator not available

[Walter M. <wb...@fe...>]

Hi,

I tried to use the Sftp example in my own code, for sending a file to a 
remote server.
But I'm getting this error on the session.connect():
===
java.security.NoSuchAlgorithmException: DH KeyPairGenerator not available
java.lang.NullPointerException

======

This is the relevant code:
====
 public boolean session(String cmd, String host, int port, String user, 
String pass,
                         String filename, String remotedir) throws 
IOException,
            UnknownHostException, IllegalArgumentException
  {
    try {
      JSch jsch=new JSch();


      // make the connection and login
      session=jsch.getSession(user, host, port);
      session.setPassword(pass);

      session.connect();  // IT DIES HERE
    
      // now open a channel with sftp as the protocol
      Channel channel=session.openChannel("sftp");
      channel.connect();
      csftp=(ChannelSftp)channel;

      // now, we need to change dir
      if (remotedir.length() > 0)
      {
        csftp.lcd(remotedir);
      }
 
      // only one way to transmit data - binary
      if (cmd.equals("put"))
      {
        sendFile(filename);
      } else
      {
        getFile(filename);
      }
 
      // now we need to disconnect
      session.disconnect();
    }
    catch(SftpException e){
      System.out.println(e.message);
      e.printStackTrace();
      return false;
    }
    catch(Exception e){
      System.out.println(e);
      e.printStackTrace();
      return false;
    }

What am I missing?

thanks,
Walter
