i did it.. but also didnt work..But i found the solution by changing the directories. Some one told me that css file shuld be placed where
jsp's are place( beconz css becomes the part of jsp). B4 this jsp's where at \webapp\template.jsp and css was \webapp\lib\style.css ................. Now placing the style.css in same directory and using background:url(images/Node.jpg) in css it started woriking fine in both IE7 and Firefox 2.0.03...
Thanks all for participating....
