My problem is simple but I am confused with this please help me.

In a JSP, I am receiving an Attribute(idsList) from Servlet1 and I want to send this Attribute(idsList) to another servlet, Servlet2 but I can do this using session.setAttribute(). My trouble is, how can we send to Servlet2 in JSP itself?

Here is my code, but it’s not working because the same request is used to set and get.
Please do the favour.

In Servlet1:

request.setAttribute("idsList",idsList);---is null

In JSP

List<Integer> idsList =(List<Integer>)request.getAttribute("idsList");
System.out.println("size of ids list :"+idsList.size());
request.setAttribute("idsList",idsList);

In Servlet2 :

request.getAttribute("idsList");---is null

    Forward your request using RequestDispatcher as shown below:

    request.setAttribute("idsList",idsList);
RequestDispatcher rd = getServletContext().getRequestDispatcher("servlet2");
rd.forward(request, response);

    You can use request.getAttribute("idsList") on servlet2.

    Do not use response.sendRedirect() to send request object.

    EDIT :

    I found a comment below your question:

    r u getting value in JSP using setAttribute? YES

    Generally, JSP are used as a VIEW perspective, so,

    IT SHOULD NOT CONTAIN BUSINESS LOGIC
