Moving resources within WEB-INF

I have a web application containing hundreds of HTML, JavaScript and image files. These files are located in the root directory:

my_root--
    -- html
    -- js
    -- images

These folders contain some subfolders.

For security reasons, I need to move all these resources to the WEB-INF folder so that they are not directly accessible.

Currently, the JSP and servlet files are already in the WEB-INF folder.

What is the easiest way for me to safely move all HTML / JavaScript / images folders to WEB-INF without breaking all links / redirecting to resources in these folders and making sure that these resources are not directly accessible?

I use WebSphere and WebLogic servers.
