To Overcome to the above problem one needs to do the below
Your files are not under the jsp folder that's why it is not found. You have to go back again 1 folder Try this:
Now examine one of your links:
<link href="../Jquery/jquery.multiselect.css" rel="stylesheet"/>
The "../" is shorthand for "The containing directory", or "Up one directory". This is a relative URL. At a guess, you have a file in /jsp/<somefolder>/ which contains the <link /> and <style /> elements.
I recommend using an absolute URL:
<link href="/RetailSmart/Jquery/jquery.multiselect.css" rel="stylesheet"/>
The reason for using an absolute url is that I'm guessing the links are contained in some common file. If you attempt to correct your relative pathing by adding a second "../", you may break any files contained in /jsp.
