In Struts 1.0, it was possible to configure an Action that told Struts to
reload the struts-config.xml file for a running app. This is no longer
true in Struts 1.1 for several reasons:
* The Struts 1.0 approach required all accesses to the configuration
information to be synchronized, which slowed down performance for
everyone (the vast majority of people don't need dynamic reloads).
* The Struts 1.0 approach re-reads the config file, but it does *not*
reload any recompiled classes. That is something that is totally
out of the control of Struts -- you should use the application reload
facilities of your web application instead (for Tomcat, see the
documentation on the "Manager Webapp").
