Introduction

This demonstrates how Java clients can connect to SFTP servers to transfer files.

Detail

SFTP and Java

SFTP is a secure protocol for transferring files. For Java clients to communicate to SFTP servers, the client side of the SFTP protocol must be implemented in Java.

It is not realistic for most applications to directly implement the SFTP protocol. Instead, it is best to acquire an implementation that is well tested and feature rich - for example, edtFTPj/PRO. The following example demonstrates how a client using edtFTPj/PRO can connect to an FTP server and list the current directory on the server. It downloads every file in the directory.

SecureFileTransferClient client = new SecureFileTransferClient();

// set params
client.setRemoteHost(host);
client.setUserName(username);
client.setPassword(password);
client.setProtocol(Protocol.SFTP);
       
client.connect();
for (int i = 0; i < files.length; i++) {
   System.out.println(files[i].toString());
   client.downloadFile(files[i].getName(), files[i].getName());
}

client.disconnect();
