How to move file from directory A to directory B in remote server?

Question

I am using JSch to connect to SFTP in a website which is made from GWT. I had read a little example of sftpChannel.get(), sftpChannel.rename(), sftpChannel.rm()

But I didn't find a solution that copy a file from remote server a directory to remote server b directory.

For example, I want to copy file from /appl/user/home/test/temp to /appl/user/home/test/. Filename = abc.jpg.

I stunned here for few hours since most of the solution from network is getting file from remote server to local, or uploading file from local to remote server.

String existingfile = "abc.jpg";
String newfile = "123.jpg";
FileDirectory = "/appl/user/home/test/";
sftp.cd(FileDirectory+"temp/");
sftp.rename(newfile, FileDirectory+newfile);

Let's say, abc.jpg is existing in /appl/user/home/test/

And I upload a 123.jpg in /appl/user/home/test/temp/.

Now, I want to move 123.jpg to /appl/user/home/test/ and remove abc.jpg in /appl/user/home/test/.

What should I do?

It seems like SftpChannel.rename(); need to use full path of file instead of cd to the directory that the file I am going to move.

String existingfile = "abc.jpg";
String newfile = "123.jpg";
FileDirectory = "/appl/user/home/test/";
sftp.cd(FileDirectory+"temp/");
if (sftp.get( newfile ) != null){
    sftp.rename(FileDirectory + "temp/" + newfile , 
        FileDirectory + newfile );
    sftp.cd(FileDirectory);
    sftp.rm(existingfile );
}
