Right, but I'm wondering what happens if 2 packages have the SAME namespace and
each have an action with the same name like:
<package name="testPrivatePages" extends="private" namespace="/test">
<action name="testAction"> etc.
<package name="testPublicPages" extends="public" namespace="/test">
<action name="testAction"> etc.
Which one gets selected?

extends attribute:
The extends attribute is optional and allows one package to inherit the
configuration of one or more previous packages - including all
interceptor, interceptor-stack, and action configurations.
http://struts.apache.org/2.0.14/docs/package-configuration.html
but a package can be abstract which means NO action available so dont
use package for assigning action
namespace attribute:
The namespace attribute subdivides action configurations into logical
modules, each with its own identifying prefix. Namespaces avoid
conflicts between action names. Each namespace can have its own "menu"
or "help" action, each with its own implementation. While the prefix
appears in the browser URI, the tags are "namespace aware", so the
namespace prefix does not need to be embedded in forms and links.
http://struts.apache.org/2.0.14/docs/namespace-configuration.html
if a request for /barspace/bar.action is made then namespace barspace is
searched for bar action
this addresses your requirement for same action name but using differing
namespace
