Method Summary

static void	closeCache() Clean up the global cache Clean up all cache threads before your stand-alone application exits, helping it terminate the parent thread instead of hanging because the cache's thread is still running.

remoteFileName - the name of the file on the remote server to retrieve, i.e test.txt

sftpFolder - remote sftp folder, for example: / or /sftpRoot or /mysftpFolder.

toLocalFolder - local filesystem folder to write the folder to C:\\myfiles\\project\\sftpProject\\writeToFolder";

serverName - sftp server name

username - sftp username

password - sftp password

Returns:

FileTransferStatus.SUCCESS or FileTransferStatus.INVALID_SETTINGS (if username or password or servername is not found)

Throws:

FileTransferException - If there is an error getting the file, catch the exception and log it or print out the stack trace or its cause for debug purposes.

For example:

String sftpFolder = "/test";
String toLocalFolder = "C:\\myfiles\\project\\sftpProject\\writeToFolder";
int status = -1;
try {
status = SFTP.getFolderCreate(sftpFolder, toLocalFolder, new BatchTransferProgressDefault(),"sftp.myhost.com", "sftp", "pass");

} catch (Exception e) {
e.printStackTrace();
//or
//ex.getCause().printStackTrace(); (Depending on what version of JDK you use)

closeCache

public static void closeCache()
                       throws FileTransferException

Clean up the global cache Clean up all cache threads before your stand-alone application exits, helping it terminate the parent thread instead of hanging because the cache's thread
is still running. YOU DON'T HAVE TO DO THIS, it is completely OK to have the global cache thread running still,
but if it bothers you about having running threads and you don't need to do SFTP-ing any more then do this.
ONLY DO THIS BEFORE THE JVM EXITS (before the main() method exits)
DON'T USE IT IF THE APPLICATION IS RUNNING WITHIN A SERVLET CONTAINER, UNLESS YOU
CAN HOOK IT TO THE SHUTDOWN MECHANISM OF THE CONTAINER. Example:

public static void main(String[] args) {
String sftpFolder = "/test";
String nameOfFile = "testStream.txt";
String toLocalFolder = "C:\\myfiles\\writeToFolder";
int status = -1;
try {
status = SFTP.getFile(nameOfFile, sftpFolder, toLocalFolder,"sftp.myhost.com", "sftp", "pass");

} catch (Exception e) {
e.printStackTrace();
//or
//ex.getCause().printStackTrace(); (Depending on what version of JDK you use)
}
try {
SFTP.closeCache();
} catch (FileTransferException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Throws:

FileTransferException
