Upload to FTP server
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.
