Hi,
It depends on what version of Finesse you are running:
1. If you are using Finesse 10.6 and above, you just need the relative URL because these files are hosted on the Finesse server itself:
<script type="text/javascript" src="/desktop/assets/js/jquery.min.js"></script>
<script type="text/javascript" src="/desktop/assets/js/finesse.js"></script>
NOTE: What you have should still work as long as you can access the src's url from the browser.
2. If you are using Finesse 10.5 and below, you need to upload these two files with your gadgets and the src will be the relative path to these files (similar to how the gadget business logic imports the .js file).
Thanx,
Denise
