i written below line in my jsp code:


<% ArrayList fileDisp1=(ArrayList)session.getAttribute("arrlist");
List list=new ArrayList();
list.addAll(fileDisp1);
Iterator iterValue=list.iterator();
while(iterValue.hasNext())
{
String dispValue=(String)iterValue.next();
%<
<a href="/DL"?FileName="<%=dispValue%>"< <%=dispValue%< </a<<%
}


inorder to get that value "dispValue" to the servlet,i wote like this:

String originalFileName=request.getParameter("dispvalue");
System.out.println(originalFileName);

when i run this ,it is printing "null" in System.out.println().
why it is so?
can anyone help?

Your parameter's name is FileName and not dispvalue; use getParameter("FileName") instead.
 
Don't get me started about those stupid light bulbs.
