File Transfer Library

The Echo3 File Transfer Library provides support for uploading and downloading files to and from Echo3 applications (client-side or server-side). It uses the the Apache Commons File Upload library to process uploaded files.

The library consists of an UploadSelect component which provides support for selecting and uploading files, and a DownloadCommand which will download a file to the user.


The File Transfer Library is licensed under the Mozilla Public License which enables the development of both open-source and commercial software with this library.
