This error means that Java runtime cannot load the applet. Did you copy lib/ folder into your server ? You should have something like :
applet_ftp.js
applet_ftp.html
applet_http.js
applet_http.html
lib/chttpclient.jar
lib/clogging.jar
lib/cnet.jar
lib/ftpimpl.jar
lib/httpimpl.jar
lib/jfileupload.jar

You have install instructions at:

Hi support team,

First, does it work with HTTP only ?
Second, are you able to open a simple HTML page with HTTPS in your browser ?
If so, then you should try WeakSSL add-on. It allows to disable certificate checks for untrusted SSL certificates.

Hello support team,

Thx for the reply, actually, with ftp the applet gets loaded but when i paste a small file in it
it gives the error:
Upload failed : java.net.ConnectException: Connection refused: connect

And when i try to open a simple html page with https it gives the error:
The connection was interrupted
The connection to localhost:8081 was interrupted while the page was loading.

i am using mozilla firefox v2.0.0.12
with ssl enabled.

i tried the weakssl files too ,but still the same errors come.

If you cannot open an HTML page withing your browser with HTTPS then the applet will have problem too. You need basic HTTPS to work with browser before trying anything else.
Do you have an URL I could check from here ?

hello support team!

I am indeed now able to open a simple html page through https on port 8181.
and when i open applet_http.html on the same port using https,the applet gets loaded, but when i
drag n drop or select a file to upload then its unsuccessful...
the following error shows up..

Upload started ...Upload failed : javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

So, what should i do now,how should i proceed..?

Ok, you're not far from the solution. You have to install WeakSSL add-on and setup the following parameter:
...
param6="weakssl"
value6="dummy"
...
<PARAM NAME="param6" VALUE="weakssl">
<PARAM NAME="value6" VALUE="dummy">

Make sure you've closed all browser windows before testing. Then you're sure that the applet is really reloaded.

If it still fails then drop an email to support(at)jfileupload(dot)com with a testing URL.
