How to get jsp:param

[Fawad Ali]

Hi All,
I have written something like this.

<jsp:include page="abc.jsp" >
	<jsp:param value="yes" name="pageRefreshed"></jsp:param>
</jsp:include>

In abc.jsp, when I try to get it by

request.getParameter("pageRefreshed");

It always gives me null. Any idea what I am doing wrong.

Thanks in advance.

All looks good to me.
Here is a full example that works for me on Tomcat7.

page1.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<h1>Test of page 1</h1>
<ul> 
<c:forEach var="item" items="${paramValues.fromPage1}">
  <li>${item}</li>
</c:forEach>
</ul>

<h2>Including page2: Giant</h2>
<jsp:include page="page2.jsp" >  
    <jsp:param value="Fee" name="fromPage1"></jsp:param> 
    <jsp:param value="Fie" name="fromPage1"></jsp:param>  
</jsp:include>
<hr/>
<h2>Including page2: Bar!</h2>
<jsp:include page="page2.jsp" >  
    <jsp:param value="Bar!" name="fromPage1"></jsp:param>  
</jsp:include>

page2.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
This is page2.  I received: ${param.fromPage1} : 

<h3>All request parameters "fromPage1":</h3>
<ul> 

<c:forEach var="item" items="${paramValues.fromPage1}">
  <li>${item}</li>
</c:forEach>
</ul>

Try accessing it with something like http://localhost:8080/MyWebApp/page1.jsp?fromPage1=HelloWorld

If this works, then double(triple) check your code. Maybe print out all the request parameters received with the following code snippet:

<h3>Request parameters:</h3>
<table>
 	<c:forEach items="${param}" var="p">
 		<tr>
 			<td>${p.key}</td>
 			<td>${p.value}</td>
 		</tr>
 	</c:forEach>
 </table>
