Is there a way to copy large files via Webdynpro FileUpload API ?

Hi,

I have created a webdynpro application in which I need to upload a large file to the machine hosting J2EE server (or any other physical file location on network).

The file size can go upto 2GB.

The normal way of using FileUpload UI feature wherein the file is uploaded as byte stream into the context of view controller fails as after 30MB of file size, the JVM runs out of memory.

Is there a way by out of this problem ?

Regards,

Sameer

    Sameer,

    WD has this problem, at least till NW04s.

    My advise: better use plain servlet for file uploads instead.

    Next, it would be much better to use desktop application or signed applet that split file up to small chunks and submit / re-submit / resume this parts. Also special file handling required at server part. 2Gb files uploads is very specific task, so it should be solved with suitable technology, browser file upload is wrong choice here.

      Sameer,

      <i>Is there is a way by which I can get the qualified path of the file which I have browsed and attached...</i>

      Some versions of IE send this informations, others - not. Neither Mozilla, nor Opera sends full path information due to security reasons.

      <i>I would like to have the FileUpload UI feature without the precise method of standard upload. Is that possible?</i>

      No

      VS

    Hi Valery,

    So do you think we can upload files upto 25 MB on these applications. Do you know of parameters in Visual Admin which will optimize this?
