List data= (List)request.getAttribute("data");


One thing to suspect is the request.getAttribute("data") returns null . Is the request originated from servlet ? or you directly hit the jsp.

And, how you map the servlet in web.xml & access the servlet from the URL?

So, How do you deploy & invoke the servlet? Inside a web container? If so we need to see your web.xml mapping and URL used to invoke the servlet.

Is the servlet invoked at any way? Run a debugger or place sysouts at strategic locations printing the info or variables of interest.

Apart from the actual problem, you should not use scriptlets. Drop them all and use taglibs and EL. The JSTL's c:forEach tag is perfectly suitable for looping over a List.
 
I agree. Here's the link: http://aspose.com/file-tools
