From the Java automatic update. First time I installed the update it was the "-oem" version. I've uninstalled the update as it was breaking the applet. When I updated again it got the "_17" version.

I am now using "1.6.0_17" but it fails with both versions.

It seems that your demo breaks as well, but not the simple demo, but the JavaScript API version. I get the exact same error. I am also using the JSAPI plugin, so I guess that's where the problem is.

Yes.
It seems that only my applet stopped working, your demo works fine. Do you know what might cause the error?

I've just updated to "1.6.0-oem" and the applet no longer works:
Exception: java.lang.NoClassDefFoundError: jfileupload/upload/client/MApplet
Please advise.

That would be great.

P.S. Is there a way of sending also the expected total file size of the file with each chunk? Or at least with the last chunk, so that the server side script can make sure the file doesn't miss any bytes.

I now think the chunk count problem was caused by the server as it doesn't happen anymore. I suspect this happens when the web server is being restarted while the user is uploading a file. Even though it is something that it doesn't happen that often, it is a problem could have been easily handled. ...

So, you suggest that the server-side script returns the id of the last chunk (for the HEAD request sent for resume) and then the applet will restart from this last id?

Yes. That would make the applet a more reliable upload tool and it doesn't seem very difficult to implement.

Customizing the server side script to skip the chunks that were already uploaded is easy. However, when struggling to upload a 2GB file over a bad connection, starting the transfer from the beginning (uploading chunks that are already on the server) will waste a few more hours so is not the best opt...

I traced the error to ProgressPanel.java, inside the "transferStarted" callback function. Seems that this happens only when "progress.info=overallprogressbar". Disabling the overall progress bar stops the array index Java error, however, the file is not uploaded correctly when a retry is needed. The...
