Using the included applet_ftp_explorer.* (modified for the appropriate url, username, password and IPv6 fix), I get a NoClassDefFoundError. All lib/* files are where they should be.

The details show: jfileupload/transfer/client/http/C

All distributions are V3.2

The Java console shows a PASV connection to the FTP server is open: The JFileUpload applet_ftp.* works as expected and was modified identically.

Any ideas?

Which license do you have? Did you mix binaries of packages from different license?
You cannot mix, it may explain the error.

This is a new server and I don't think I've set up the registration yet. Ultimately, this will be a Pro installation. Will JDiskExplorer not work in demo mode?

The binaries are those from the download links on the respective product pages.

Now that you mention it, I think I have a V2.x Pro registration.

Ok, it should work then. Does the online JDiskExplorer work for you?

The online demo of JDiskExplorer works as expected.

Found the problem in 3.2. Here is the fix:
Just add ",lib/httpimpl.jar" into all ARCHIVE parameters and make sure httpimpl.jar is available in lib/ folder.

That fixed the problem!

Thank you for your help.

I use the explorer, but I am not a programmer, can you show me where to put this information so that the applet works correctly without the error?

I'm having the exact same issue. Tried the solution by including lib/httpimpl.jar into all ARCHIVE parameters and placing httpimpl.jar in lib/ folder. Still I got the "NoClassDefFoundError" error.
Will it work with the unregistered version?

I'm using:
Java Plug-in 10.51.2.13
JFileUpload 3.2

Java console:
[INFO] MApplet - JFileUpload 3.2 Build FINAL.001
[INFO] MApplet - CustomSM enabled

[INFO] E - Control encoding: ISO-8859-1

It should work, are you sure you've updated all 3 ARCHIVE parameters in JavaScript with the missing lib?
