Access to Environment Entries (java:comp/env)

[DA...@Nationwide.com]

Hi group,

I want to be able to access Tomcat's Environment Entries in the Cocoon 
sitemap the same way I access my jdbc connection.

For instance, I want to be able to add via the Tomcat administrator:

        Name:           ldapServerUrl
        Type:           java.lang.String
        Value:          ldap://some.server.ineed

And then in the sitemap.xmap, say in an ldap transformation, be able to 
have something like:

        <map:parameter name="serverurl" value="jndi://ldapServerUrl"/>
  or
        <map:parameter name="serverurl" 
value="java:comp/env/ldapServerUrl"/>

to reference what's in the environment entries.  I am currently setting 
this value, and others, using the <global-variables> section in the 
sitemap, so I wind up with:

        <map:parameter name="serverurl" value="{global:ldapServer}"/>

but I need to have some of these variables in a spot that my server 
administrator can change their values without touching the application 
files.

I have looked through the docs on cocoon.apache.org and 
wiki.cocoondev.org, but couldn't find anything other than setting up the 
jdbc connections.

Thanks!
David Day
