Try this,
suppose my MAP is :-
Map countryList = new HashMap();
countryList.put("United States", "Washington DC");
countryList.put("India", "Delhi");
countryList.put("Germany", "Berlin");
countryList.put("France", "Paris");
countryList.put("Italy", "Rome");
request.setAttribute("capitalList", countryList);
So in JSP ,
Country: ${country.key} - Capital: ${country.value}
Hope this helps !
