[Pointeman]

I have a master pages ASP.NET web site.

I placed all the .jar files in the root/admin/lib folder and placed both "applet_http.html" and "applet_http.js" in the root/admin folder...

[Web Structure]
root / (unsecure public dir)
root / admin (Secured directory)
root / admin / Lib
root / images
root / temp

I recieve the following error on the java applet after opening the applet_http.html page.

Q. Do I have all the needed files in all the right places?

This error means that the JAR file on server is corrupted. You might had an issue we you transferred JAR files. Did you a use a FTP tool ? If so then transfer must be in BINARY mode.

I downloaded JFileUpload from your web site and unzipped it into our test web server.

Q. Do we have the correct file installed in the correct directories?

[Pointeman]

Okay. Installed the files and /lib directory in a new web on our development pc and the applet opens and allows selecting multiple files.

Q. Where is "relativefilename" and the process.jsp server-side script?

/documentation/faq.html#7
How to re-create folders structure on server-side when uploading a folder with multiples files and subfolders ?

I have an ASP.NET web site and would like to use my own method to process the files.
Q. How do I use JFileUpload to start my own file handling script?

Q. How can I have JFileUpload simply place all uploaded file into a /temp folder?

Sorry for all the questions...

[support]

First you have to enable this feature is the applet. Si, update the JavaScript to add:
<PARAM NAME="folderdepth" VALUE="-1">
<PARAM NAME="param4" VALUE="relativefilename">
<PARAM NAME="value4" VALUE="true">

Second, use a script that supports this feature. You have an ASP.NET free sample at:
http://www.jfileupload.com/products/tools/index.html

Finally, it's in the ASP.NET that you select in which server folder files (and folders) will be uploaded.

[Pointeman]

Okay, downloaded the .NET example and tried it's examples.

Q. Is there any way to show just a single button to open the file-selection dialogbox then the progressbar shows the process?

[support]

You mean remove the info panel (with text) and the cancel button, correct ?

[Pointeman]

Yes... Can this be done?

[support]

Yes, cancel button can be removed by commenting the following line in i18n.properties (it means that you're using "resources" parameter):
progress.button.cancel=Cancel

You can also remove info panel with:
<PARAM NAME="hideinfo" VALUE="true">
However, drag and drop won't work because it works with the info panel. File selection button will continue to work.

Okay, thanks. Time for a new post..
