以下代码适用于localhost到远程服务器。但我的应用程序在单独的服务器上运行，所以我需要从remote1服务器中选择文件，然后将其放在remote2服务器中。如何处理J2SSH。

不确定我理解你的问题......

如果您只有SFTP访问两个服务器，并且您的代码在本地运行（在客户端上），那么您唯一的选择是下载文件并将其上传到另一台服务器。如果您具有对server1的SSH访问权限，则可以创建一个脚本，该脚本将上传/下载文件到服务器2或从服务器2下载。

如果您的代码在server1上运行，并且您需要将文件从server1上传到server2，那么当您将代码从client1上传到server2时，它与当前情况有何不同（除了本地路径不同）？

j2ssh远程到远程文件传输
