Problem with Javascript Containing a Relative Path--I need an Absolute Path

Dear Experts,

I have a challenge that I’m not sure I’ll be able to solve, but I thought if it was possible, someone here would know.  Here’s my issue:

I purchased a really nice script that slices HTTP uploads into smaller manageable pieces. I use it for clients who need to share large files, but find FTP too cumbersome, and it also makes large file uploads possible on a shared server. This is the product:  http://upload.thinfile.com/resume/

It works great, but only in a relative path environment.  I now have a couple of Wordpress sites that I’d like to incorporate this script on (in conjunction with a password protected page) but as you can guess, since I don’t have full path names for pages the script doesn’t work. I really don’t want to force Wordpress to show the full path name for each link, so that isn’t an option (and I'm not sure that would work anyways).

I sent an email to the company and they’ve ignored me, which is why I thought I would reach out to EE.

The script is essentially made up of 5 files:

applet.php
slice.php
ThinSlice.jar
thinupload.properties
embed.js

I imagine the settings that control the relative path are in the .jar file, but I have no experience with this type of file. I unzipped all the files to tried and take a look, but there are 38 .class files and they look to be encrypted.

I guess my long-winded question is, does it sound like this is anything that I can control/change, or does it seem more like these settings are set in stone and I’m out of luck?

I originally thought the issue was with the applet or embed.js file which I’ve pasted below. But even when I change the relative paths to absolute paths it still doesn't work, which is why I’m guessing the REAL issue is in the .jar file.

---------------------------

I set up a testing site here:

Page with Absolute Path that works right:
http://www.dzinentertainment.com/wp-content/themes/default/client-manager.php

Identical page in Wordpress that doesn't work right:
http://dzinentertainment.com/client-manager/

Here is a zipped folder with the 7 files that it takes to work:

http://dzinentertainment.com/sliced-upload.zip

I used these identical files for both pages above.

While I was setting up this test, I did copy the error message that comes up on the Wordpress page (you can see it there). I've pasted it below.

I hope this gives more helpful information.

Hi Preculopsis,

Thanks very much for your suggestion. I set this up in the header:

<BASE HREF="http://www.dzinentertainment.com/wp-content/themes/default/" />

But the applet still doesn't load here:

http://dzinentertainment.com/client-manager/

It still shows this in the error:

 failed:http://dzinentertainment.com/client-manager/com/thinfile/upload/ThinSlice.class

Another idea might be to pop the sensitive html in an iframe, using your absolute path - not very nice but could work.

Preculopsis,
Sorry it took me so long to award points. It took me a month to test your theory about iframes, but it worked PERFECTLY. Thank you SO much for your help. Thank you for a simple, but effective answer to this question that has been haunting me for months!
