Getting a Request Parameter Using JSTL in a JSP Page
When using the JSTL's expression language (see
Enabling the JSTL Expression Language in a JSP Page), the request parameters
are made available in the implicit object param. This example
demonstrates how to include the value of a request parameter from the
query string or posted data in the generated output:
If the page was accessed with the URL:
the resulting output would be:
<%-- Declare the core library --%>
<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %>
<c:choose>
<c:when test="${empty param.name}">
Please enter your name.
</c:when>
<c:otherwise>
Hello <b><c:out value="${param.name}" /></b>!
</c:otherwise>
</c:choose>
http://hostname.com/mywebapp/mypage.jsp?name=John+Smith
Hello <b>John Smith</b>!
this does not work for the string that is retrieved from HttpRequest.getQueryString().
so assume it works for data stored in HttpRequest.getAttribute() or HttpRequest.getParameter()...but unfortunately need the first one right now ;^)
