Try this:
<%
HashSet<String> mySet = new HashSet<String>();
mySet.add("Str1");
mySet.add("Str2");
mySet.add("Str3");
mySet.add("Str4");
mySet.add("Str5");
mySet.add("Str6");
mySet.add("Str7");
// putting the variable in the request scope
request.setAttribute("mySet",mySet);
// could put it in the page scope like this
pageContext.setAttribute( "list", vList );
%>
<%-- normally str would be set in the page scope, so specify the request
scope --%>
<c:forEach var="str" items="${requestScope.mySet}" scope="request">
<%-- here, you're looking for the variable "str" in the request scope
--%>
<% String str = (String)request.getAttribute("str"); %>
<p>
<%= str %>
</c:forEach>

Subject: Var for c:forEach loop is always null
Hello:
According to the c:forEach doc, the var attribute of the c:forEach tag
has nested visibility.
What does that mean?
I am trying to access the current object of the iteration
and always getting null.
Here is an example:
<[EMAIL PROTECTED] language="java" %>
<[EMAIL PROTECTED] import="java.util.*" %>
<[EMAIL PROTECTED] uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %>
<%
HashSet<String> mySet = new HashSet<String>();
mySet.add("Str1");
mySet.add("Str2");
mySet.add("Str3");
mySet.add("Str4");
mySet.add("Str5");
mySet.add("Str6");
mySet.add("Str7");
request.setAttribute("mySet",mySet);
%>
<c:forEach var="str" items="${mySet}">
<% String str = (String)request.getAttribute("str"); %>
<p>
<%= str %>
</c:forEach>
The value of str is always null.
How can I fix this?
Thanks,
Neil
