Here's the correct path required.
I guess, what you call "LocalFolder" above is "IndiaMap", but make sure 
that this relative URL (so base url of the jsp page + /IndiaMap/ leads 
to the corresponding folder.

The HTML page is mapped directly to the file system; the JSP-file is 
mapped differently through the java aware web server.
One possibility is to use the complete URL here, so instead 
"IndiaMap/${z}/${x}/${y}.png" use 
"http://complete-url-like-you-see-it.in/the/image/properties/on/the/working/html-file/IndiaMap/${z}/${x/${y}.png", 
where - sure, IndiaMap/... should not be doubled.
