Fileupload Applet Issue with Firefox 15:

When uploading a file using our application, file that is being uploaded is hashed using a signed Applet. This is working fine in IE and FF version lower than FF15.

Signed applet needs to hash file contents but it is is unable to read the full path of the uploaded file, and thus failing. Applet expects the full path of the file that has been uploaded

Is there any way to get the full file path?

This is a Java applet? And it's definitely a change in Firefox 15 (i.e., problem exists in Fx15 in the previous JREs, and does not exist in Fx14 in the current JRE)?

Hi Jscher2000,

Yes, issue does not exist in FF14 and lower versions, e.g. Ff3.6.x even with current JRE 1.7.

Any solution you can suggest?

I don't do any plugin-content development myself, so I'm not familiar with any special issues in communications between applets and Firefox.

Is the upload control part of the applet or an <input type="file"> in the page? There seem to be frequent changes with the latter.

Sounds like a 'victim' of the XPCOM UniversalXPConnect changes caused by this bug.

Hi cor-el,

Seems like it. I was googling to see and came across XPCOM also. Is this really a bug or a new feature?

Is not a new feature and not really a bug, but rather a security change that they have cleaned up code and removed the ability to use UniversalXPConnect that made it possible in older Firefox versions to get enhanced privileges.
That is no longer possible, so any code that relies on it will fail silently.
You will now require an extension to run any code that requires enhanced XPCOM permissions.
