Right now it's just documented in the javadocs and the DTD -- but it's
really simple. When the controller servlet is first stated, it will
instantiate all the plugins you have defined and call the init() method of
each one. Likewise, when the controller shuts down, it will call the
destroy() method of each previously instantiated plugin. Essentially,
your plugin has exactly the same lifecycle characteristics as the
controller servlet itself.
The struts-config.xml file for the struts-example application in 1.1 has a
plugin for the "user database" object. You can take a look at this to see
how plugins are configured.
One detail I glossed over, though -- you cannot actually call an Action in
your plugin's initialization, because that requires having a request and
response available. However, you can do whatever initialization that you
would have done in that action, by pulling that logic out into separate
classes.
