Hi,
I am new to the mailing lists and am not sure if this might better be
posted to the developer list, but thought I would try here first. Any
guidance would be very much appreciated.
We have implemented a Magnolia CMS site (with Version: 2.1 Build:
1454 on a Red Hat Linux server running Tomcat 5.0). We have been
happy with pretty much everything we have seen and been able to do,
EXCEPT one nagging, potentially show stopping problem........
We have implemented a custom tag to provide top header
JavaScript-based Milonic (www.milonic.com) menu-ing. We have used the
"simpleNavigation" tag code as the basis of our new tag and all works
well except "periodically" (once/twice a day) the menu-ing disappears
from Author and Public instance pages and/or parts of the JS are
displayed in the browser window as (uninterpreted) text. I see no
correlation between page activation or author activity. It appear to
occur randomly after some nth request fo a page. When the problem
occurs, examination of the page source code in the web browser
indicates that none or some parts of the JS output of our tag has not
been included in the page.
The problem clears is the web application or Tomcat itself is
stopped/started - the top level menu code is output and appears
properly on all pages and continues to do so for an indeterminate
time/number of site accesses.
I have read with some concern the various postings about caching and
web browser refresh issues and hence have turned caching off in both
Author And Public instances thus: server > cache > level1 > active = false
AND include the following in the top of each JSP template....
<meta content="text/html; charset=iso-8859-1" http-equiv="content-type"/>
<meta content="no-cache" http-equiv="cache-control"/>
<meta content="no-cache" http-equiv="pragma"/>
<meta content="0" http-equiv="expires"/>
We call our custom tag "milonicTopNavigation" in a our JSP page templates thus:
<jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page";
xmlns:cms="urn:jsptld:cms-taglib"
xmlns:cmsu="urn:jsptld:cms-util-taglib"
xmlns:c="urn:jsptld:http://java.sun.com/jsp/jstl/core";
xmlns:fmt="urn:jsptld:http://java.sun.com/jsp/jstl/fmt";>
<jsp:directive.page contentType="text/html; charset=utf-8" />
<jsp:text> <![CDATA[<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";> ]]> </jsp:text>
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
<head>
<c:import url="/templates/jsp/codarra/global/head.jsp" />
<cmsu:milonicTopNavigation startLevel="1" />
</head>
<body>
Any ideas anyone? Banging my head against a brick wall at this point.
How does Tomcat actually load the site pages - why could execution of
a custom tag work happily and then but suddenly start failing until a restart?
Does Tomcat perhaps do some caching independent of what Magnolia is doing?

The only thing I may think of is that the generated html is not valid. Have you
double checked this?
