I forgot to add the simplest way in an Action class:

MessageResources resources = getResources(request);

resources.getMessage("keyName");

If you're just looking for the values, grab it as a resource bundle. Here's
how I grab it in a Business Delegate:

    // Get the application's messages resources
    ResourceBundle resources =
ResourceBundle.getBundle("ApplicationResources");
    String appDBVersion = resources.getString("webapp.db_version");

And then of course, there's errors and messages - where it grabs it
automagically:

        errors.add(ActionErrors.GLOBAL_ERROR,
                   new ActionError("errors.existing.user",
                                   userForm.getUsername(),
                                   userForm.getEmail()));

        messages.add(ActionMessages.GLOBAL_MESSAGE,
                     new ActionMessage("user.deleted",
userForm.getEmail()));

And lastly, you can get it from the servlet context in a servlet outside of
struts:

        MessageResources resources =
            ((MessageResources)
getServletContext().getAttribute(Globals.MESSAGES_KEY));

        resources.getMessage("userFormEx.username");


HTH,

Matt

When Struts load, it grabs application.properties and stores it's keys and
values somewhere.  From within an action class I need to access a value in
application.properties.  How could one do this?
