Pass parameters from one page to another

This is the issue, I have a JSP which helps me to generate a URL to change the Locale, to switch between Spanish and English, but I have a JSP (maybe more) which is displayed based on a Parameter, because shows the details for an Object based on idObject.
This is my original JSP (So each time I clicked the link, the page was refreshed, but missing the param, obviously the content was never displayed - duh!) <fmt:message key="button.locale"/>: <c:url var="englishLocaleUrl" value="${urlBase}"> <c:param name="locale" value="en" /> </c:url> <c:url var="spanishLocaleUrl" value="${urlBase}"> <c:param name="locale" value="es" /> </c:url> <c:out value="${englishLocaleUrl}"/><fmt:message key="locale.english"/> <c:out value="${spanishLocaleUrl}"/><fmt:message key="locale.spanish"/>

The fix is really simple, just add more params to each URL, by using JSTL :) Like this (creating dynamically my params) <c:forEach items="${param}" var="pageParam"> <c:param name="${pageParam.key}" value="${pageParam.value}" /> </c:forEach> <fmt:message key="button.locale"/>: <c:url var="englishLocaleUrl" value="${urlBase}"> <c:param name="locale" value="en" /> <c:forEach items="${param}" var="pageParam"> <c:param name="${pageParam.key}" value="${pageParam.value}" /> </c:forEach> </c:url> <c:url var="spanishLocaleUrl" value="${urlBase}"> <c:param name="locale" value="es" /> <c:forEach items="${param}" var="pageParam"> <c:param name="${pageParam.key}" value="${pageParam.value}" /> </c:forEach> </c:url> <c:out value="${englishLocaleUrl}"/><fmt:message key="locale.english"/> <c:out value="${spanishLocaleUrl}"/><fmt:message key="locale.spanish"/>
