Come si recupera un parametro con jstl
come già facevo con jsp: request.getparameter("valore") ?

codice:
<%@ page contentType="text/html" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<f:view>
<html>
<head><title>Complete Person Information</title></head>
<body leftmargin="0" rightmargin="0" topmargin="40" bottommargin="0">
<center><h:form>
<h:panelGrid width="375px" bgcolor="#e6edfd" columns="2" border="0">
       <f:facet name="header">
            <h:outputText value="You have entered information :"/>
       </f:facet>

        <h:outputText value="Name: " />
        <f:param name="valore" value="$(param.valore)"/>
        <h:outputText value="#{valore}" />
        
       <h:commandButton value="Modify" action="details" />

</h:panelGrid>
</h:form></center>
</body>
</html>
</f:view>
