404 error while refreshing using jsp servlets

Hi im new in jsp/servlets, i have a basic question about relative or abselute path: i have the following hierarchy, using netbeans:

Web Pages
|  |-Status
|     |-clientRequests.jsp
|  |-index.jsp
|  |-WEB-INF
|     |-professional.jsp

index.jsp and the Status folder and WEB-INF folder in root path. inside the Status folder we have the clientRequests.jsp file. inside the WEB-INF folder we have the professional.jsp file.

in the index.jsp i have done dispacher to professional.jsp, inside professional jsp i have <iframe src="Status/clientsRequests.jsp"></iframe> inside the clientsRequests.jsp i have 

<%
        response.setHeader("Refresh", "5;url=../index.jsp");  
%>

that means that every 5 sec will be refresh to the clientsRequests.jsp file, and then go to the "controller" which is index.jsp. now what i wanted to be that every 5 min, only the iframe refreshed and not the hole page. my problem: in the second refresh it gives me 404.

i tried to play with that and i did something ugly like:

String a = (String)session.getAttribute("nav");
if(a == null){
    session.setAttribute("nav", "aaa");  
    response.setHeader("Refresh", "5;url=../index.jsp");  
}else{
    response.setHeader("Refresh", "5;url=index.jsp"); 
}

and its working, but i dont want wo leave that like this way... do you have any suggestions? thank you!

one Alternative would be to move the clientRequests.jsp to the same level as index.jsp. That way in your code you can always do this

response.setHeader("Refresh", "5;url=index.jsp");

One advantage is with this set up , the <iframe src="Status/clientsRequests.jsp"></iframe> can be added to any of the JSP pages in your application and there is no change/impact in the servlet code

Somehow your response is setting header for the parent of the iframe too. Put the below line in the of clientsRequests.jsp.

<meta http-equiv="refresh" content="5">
