Is it possible to reference scriptlet variables from a JSTL tag?

[Richard Berger <ri...@attbi.com>]

For example...
<jsp:useBean id="delegate" scope="page" class="golf.util.ResourceDelegate"/>
....
<% Collection coll = delegate.getReservationsForUserID(userid); %>
<c:forEach items="${coll}" var="teeTime">

I do not seem to be able to get this to work.  Am I missing something, or do
I need to do this all in scriptlet world and forget about JSTL for this
problem?

Thanks much!

PS - Many apologies if this is not the way to post to this mailing list - it
is my first try and there was no FAQ or user info for this list.

JSTL actions (or any other custom action) have no way to access
scripting variables, only "scoped variables". A scoped variable is the
same as an object stored as an attribute of any of the JSP scopes: page,
request, session and application. So you need to modify your code
like this:

   <%
     Collection coll = delegate.getReservationsForUserID(userid);
     pageContext.setAttribute("col1", col1);
   %>
   <c:forEach items="${coll}" var="teeTime">

Tags, whether JSTL or not, cannot read scripting variables.  Instead, you
need to make them scoped attributes, as with

 <% pageContext.setAttribute("coll", coll); %>
