Static Access to MessageResources or Bundles?
Is there any way to statically access fields from resources defined in
Struts?
In other words, I would to be able to access terms stored in properties
files without needing a ServletRequest. My application exists within a
servlet container, and utilizes Struts. However, I have processes
running that are independant of incoming requests.
Any ideas?

The commons-resources project is intended to provide a generalized
framework for handling messages like this; it was factored out of
Struts, and one day, perhaps Struts will depend upon it in favor of
the original implementations.
I don't think commons-resources has seen a full 1.0 release yet, but
it's usable.
The Spring Framework also provides a generalized message resource
handling mechanism which is well suited to use independently from the
Servlet API. Spring, of course, has seen a full release, and is
closing in on its 1.2 release. Of course, it carries with it a lot
more than just message handling, but you can selectively install
sub-jars if you don't want to carry around the whole thing (or risk
your team depending on some part of it that you aren't ready to
depend upon just yet.)
Either of these would require some more set-up to make the resources
available, but either should be fairly straightforward to implement.
Spring makes it trivial to provide your business layer classes with
implementations of the resource loader, as long as you let it manage
those classes.

Because at least in theory, you have no guarantee that the Message
Resources are coming from a properties file. Some people want to be
able to get them from a database, or from an XML file. These
features aren't used all that often, but the design is to support
them.

Well, I have a solution.
String bundle = "common" ;
String key = "date" ;
MessageResources.getMessageResources(bundle).getMessage(Locale.EN, key);
This is very straightforward.
So why does Struts prefer to store and access the resources through the
ServletContext? Is this faster?

Search for org.apache.struts.util.MessageResources
I guess this should work:
MessageResourcesFactory messageFactory =
MessageResourcesFactory().createFactory();
MessageResources messages =
messageFactory.createResources();

Maybe a generic servlet style scheme similar to this:
web.xml
<init-param>
<param-name>properties</param-name>
<param-value>/path/to/properties/file/webapp.properties</param-value>
</init-param>
use servlet config instance at servlet init() to load (once):
props =
(Properties)config.getServletContext().getAttribute("webapp.properties");
then retrieve (as needed):
props.getProperty(key);

I would to be able to access terms stored in properties
files without needing a ServletRequest.
