JSP request is not pass to another jsp page when using jquery load method

I encountered a problem when using jquery's load() method in JSP page. In the first page, I am
trying to set attribute list1 into request and use load() to load contents of page 2 into page 1's
"#content".


list1 = new ArrayList
(); request.setAttribute("list1", list1); %>
$("#content").load("page2.jsp");



In second page, list1 is being retrieved from request and do some processing before being output by
out.println()


list2 = (ArrayList
) request.getAttribute("list1"); // process something here if (list2==null){
out.println("list2 is null"); } else { // out.println() contents of list2 } %>
Then here is where the
problem lies.
request.getAttribute("list1")
in page 2 returns null pointer, and after some research I
found that request is not being sent to page 2 so I cannot retrieve "list1" from request.

I cannot use
request.getRequestDispatcher("page2.jsp").forward(request, response)
in page 1 as
it will redirect me to page2.jsp, that is not what I intended to do.

Is there any work around that I can pass request to page 2 so that I can retrieve the data? Thanks.
