As I undestood you need dynamically change your background image. And you need to do it from java (jsp). If you need to do it one while page loading you can put background image to request attributes in servlet:

request.setAttribute("bgImageUrl", "your_url");

And in jsp:

$("#fullBG").css("background-image", "url(${bgImageUrl})");

If you need to do it without page reload: use ajax.
