-----Original Message----- From: Kris Schneider [mailto:[EMAIL PROTECTED] Sent: May 27, 2004 3:26 PM To: Tag Libraries Users List Subject: Re: Associative array variable in JSP tag file I haven't had time to play with tag files much, but here's a quick example that may help: map.jsp: -------- <%@ page contentType="text/plain" %> <%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %> selected.client before: '${selected.client}' <tags:map> selected.client during: '${selected.client}' </tags:map> selected.client after: '${selected.client}' map.tag: -------- <%@ variable name-given="selected" variable-class="java.util.Map" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <jsp:useBean id="selected" class="java.util.HashMap"/> <c:set target="${selected}" property="client" value="checked"/> <jsp:doBody/> output: ------- selected.client before: '' selected.client during: 'checked' selected.client after: '' The reason the value is only updated within the body of the tag is because the default scope for the variable directive is "NESTED". That also means you need to do something like use the <jsp:doBody> action to actually process the body in the calling page and update the value.
