I'm using Cocoon 2.0.1 on Tomcat 4.0.1. I've set up my main sitemap to
match different sub-uris and then mount a sub-sitemap for the corresponding
sub-directory the way it's done in the cocoon sub-sitemap example. In
addition I want to do user authentication for a whole subsitemap in the
main sitemap this way:
<map:match pattern="sub/**">
<map:act type="session-validator">
<map:parameter name="descriptor" value
="context://descriptors/params.xml"/>
<map:parameter name="validate" value="username"/>
</map:act>
<!-- something was wrong, redirect to login page -->
<map:redirect-to uri="../login"/>
</map:match>
So far so good, although I do not understand why I must use
<map:redirect-to uri="../login"/> with prefix '../' in my main sitemap,
maybe that's already a hint for a problem.
What I wanted to do is to access the sitemap param 'username' in the
subsitemap, which does not work. I tried the following entry in my
subsitemap:
<map:match pattern="*.html">
<map:generate src="docs/{1}.xml"/>
<map:transform src="../stylesheets/mystyle.xsl">
<map:parameter name="use-request-parameters" value="true"/>
<map:parameter name="username" value="{../username}"/>
</map:transform>
<map:serialize/>
</map:match>
That throws an Exception when calling a subsite page (being already
authenticated, of course):
org.apache.cocoon.sitemap.PatternException: error occurred during
evaluation of expression "{../username}" at position 1 Index: -1, Size: 1

I also tried to use {username} instead if {../username} which of course did
not work because there is no sitemap param username on the param stack top.
Did I expect the wrong behaviour in param-handling when using <map:mount>
or did I do any other mistake?
Thanks for help,
