howto make html:link dynamic select item of map ?

[Nakata kokuyo]

hi good day,

i have a hashmap which hold the information for menu name, and it look like following :

<%
 Map map = new HashMap();
             for (int i = 0; i < retMenuList.size(); i++) {
                 Module module = (com.test.Module) retMenuList.get(i);
                  map.put(module.getForward_url(), module.getForward_url());
             }
 
pageContext.setAttribute("retMenuLists",retMenuList);
pageContext.setAttribute("menumap",map);
 
%>
 

which may result as follow :
map.put("menu1","menu1");
map.put("menu2","menu2");


then i have a jstl foreach loop for create link as following

 <c:forEach  var="module" items="${retMenuLists}"  >
        <html:link action="${module.forward_url}" paramId="menuname" paramName="${module.forward_url}" styleClass="bigtab"> <c :-o	 ut value="${module.top_menu_name}"/> </html:link>   
     </c:forEach>

this created link is fine if i have hard code it with
request.setAttribute("menu1", "menu1");
request.setAttribute("menu2", "menu2");

and the result will show mke the link pass a parameter to other page which is something like this "menu1.do?menuname=menu1",

but my problem is , i try to avoid hardcode it into request, and prefer to make it dynamically when i have a menu name with "menu1", it will go Hashmap find the key for "menu1" and insert into "paramName" property

can someone guide me how to do so ? thank you
