Upload to FTP server

(since 2.13.0)

Powered by Jakarta Commons Net

In order to upload to FTP it is necessary to specify additional jar archive (ftp_z.jar, download):

<applet id="jumpLoaderApplet" name="jumpLoaderApplet"
width="800" height="600" mayscript>

and ftp protocol for UploaderConfig.uploadUrl parameter. It is also possible to specify username, password, remote directory and options (in query string), for example:


If username/password contain special characters (such as @), this should be urlencoded.

Supported following options:

  • passive — use passive mode for transfer

FTP uploads are resumable — if remote file with same name exists, this would be resumed.

Due to ftp protocol limitations some jumploader features are not applicable for ftp uploads, such as custom attributes, partitioned upload.
