Applet Not Writing to FTP

I've been beating my head against this wall for 8-10 hours, today. Please help if you can!

I have a java applet which uses an Apache FTPClient to download some information from a file, then use that information to write a file onto that same FTP server. These are all located in the same directory as the applet itself. When I run this applet in my Eclipse Applet Viewer, it works perfectly, writing the information to the FTP. When I load it from the browser, however, it hangs at that point and never writes. I've signed the only .jar file, and nothing seems to be working. Is there anything else I might be missing?

No error messages? Are you using chrome? If so you can use the debugger to check out the stack trace. If I were a betting man I would put my money on a SecurityException since applets aren't allowed to read/write to a physical drive (hackers would have a field day if they could).

If would also be worth while logging you program so you can see exactly where it has failed.

What Applets Can and Cannot Do (The Java™ Tutorials > Deployment > Java Applets)

Regarding "What Applets Can and Cannot Do...," I've read over that stuff, and the impression that I had was that if I signed my applet, it wouldn't have the same restrictions once the user accepted it, right?

Ok - Java console is telling me it cannot locate the Apache class that I'd installed -

AWT-EventQueue-2" java.lang.NoClassDefFoundError: org/apache/commons/net/ftp/FTPClient


Why might this be happening? I compile fine and include all compiled classes in my jar...

What are you doing that could be restricted?
I don't know if sending a request to the server that the applet is loaded from is a problem.
Doing file I/O on a local PC is a problem.

You forgot to say if there are error messages in the browser's java console.
Be sure to look. Copy and paste the full text of the messages here.

IT WORKS! Sorry for wasting everyone's time - as soon as I checked the log, I realized it wasn't finding the apache library because I had to include that jar on the server... Thanks for helping everyone! :) (And sorry for the cross posts...)

Ok - read the post about cross-posting, and it does make sense. All apologies, and thanks for the help.
