Re: Pass A String From Servlet And Write Out Its Value in JSP

[Brice Ruth]

The easiest way to do this isn't with a Struts tag, per se, but with a 
JSTL tag, I think - just use the JSTL 1.0 (or 1.1) tag library like so:

<% taglib uri="http://java.sun.com/jstl/core"; prefix="c" %>

<c:out value="${c}"/>

That *should* work for either a session-scoped variable or a 
request-scoped variable.

If you need to print out a value from a scriptlet (which is where 
keyValue is being defined) - you should store that value in pageContext, 
like so:

<%
pageContext.setAttribute("keyValue", keyValue); // first parameter can 
be anything you want to name it
%>

<c:out value="${keyValue}"/>

That should be it!

My servlet has a String called 'category'.  I want to
pass the String to a JSP.  Therefore, I have the code
shown below in the servlet:
session.setAttribute( "c", category );
OR
request.setAttribute( "c", category );
And, I do the following in my JSP:

<% String keyValue = (String)session.getAttribute( "c"
); %>
OR
<% String keyValue = (String)request.getAttribute( "c"
); %>
How do I write out keyValue in my JSP in Struts?
