Large file downloads using a Java applet

I was instructed to implement large (2gb +) file downloads through a web browser. After evaluating various technologies, java applets look like a way forward (only one that provides proper access to the local disk). I was wondering if anyone could recommend a third-party file upload application that we can use as a base? requirements

  • Decent user interface, ideally we want something similar to facebook uploader.
  • Can handle large (2gb +) files
  • Renewable downloads
  • We used the source to distribute it to our needs (do not pay for it)

You may be looking for jupload .

Update: I'm not sure that it has the same nice interface as you hope, but if you do not want to create a custom solution, for example, I have its best option.

Just a hint, maybe it's obvious, I don't know: P

It's nice to send a large file in chunks like 2mb, and on the server side you just add bytes to the target file. The server knows what bytes it needs, and if the download is interrupted and continues later, the server can simply send a message about which bytes to start downloading the file again. Then we get the ability to resume (is this the word ?: P) and the security of large HTTP downloads (since in fact we send a lot of smuller downloads, and each download is checked for the correct size on the server).

We wrote an implementation like this once, with a Java applet as a client and PHP on the server, I will see if I can dig it out as a link for you: p

Not really a solution: from experience, you may encounter the following problems:

  • problems downloading via HTTP
  • problems downloading through proxies

I just wanted to tell you about these two cases so that you can check them when evaluating the solution.
