Failed to override global naming resources in specific app!
Hi,
description
webapp definition cannot override global one, even though
override attribute set to true.
Why?
Is that the right way to define resource for common use and
redefine it within specific webapp?
scenario
version: 5.5.20
global definition in conf/server.xml:
<GlobalNamingResources>
<Environment name="maxTTL" value="500"
type="java.lang.Integer" override="true"/>
</GlobalNamingResources>
webapp definition in WEB-INF/web.xml:
<env-entry>
<env-entry-name>maxTTL</env-entry-name>
<env-entry-value>800</env-entry-value>
<env-entry-type>java.lang.Integer</env-entry-type>
</env-entry>
webapp reference of global in META-INF/context.xml:
<Context docBase="helloapp2" debug="5" reloadable="true">
<ResourceLink name="maxTTL" global="maxTTL" type="java.lang.Integer">
</ResourceLink>
</Context>

Bcz if no resourcelink into my webapp, the global resource will not be
visible.
And I tried to remove it, my jsp only got env-entry value from web.xml.
In online help: The GlobalNamingResources Component
It said like this:
**************************
The GlobalNamingResources element defines the global JNDI resources for
the Server.
These resources are listed in the server's global JNDI resource context.
This context is distinct from the per-web-application JNDI contexts
described in the JNDI Resources HOW-TO. The resources defined in this
element are not visible in the per-web-application contexts unless you
explicitly link them with <ResourceLink> elements.

Why the ResourceLink? What happens if you remove this?
