printing taglib variables from inside a scriptlet

["Carole E. Mah" <ca...@mama.stg.brown.edu>]

How does one print taglib variables from inside a scriptlet?
Is it possible?

e.g. the following does not work -- it returns the error
 "Undefined variable: test"

thanks!

<%@ page import="java.io.*,java.util.*" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

<c:set var="test" value="foobar" />

<%
try {
  PrintWriter outFile = new PrintWriter(new FileWriter("blort.txt"));
  outFile.println(test);
  outFile.close();
}
catch (IOException e) {
  System.err.println(e);
  System.exit(1);
}
%>

You need to retrieve the scoped variable manually, for it isn't a
scripting variable.  For instance:

    pageContext.findAttribute("test")

Note that this syntax is indeed inconvenient, which is why the JSTL EL is
useful in the first place.  :-)
