org.apache.struts.action
public interface PlugIn
A PlugIn is a configuration wrapper for a
module-specific resource or service that needs to be notified about
application startup and application shutdown events (corresponding to when
the container calls init
and destroy
on the
corresponding ActionServlet instance). PlugIn
objects can be
configured in the struts-config.xml
file, without the need
to subclass ActionServlet simply to perform application lifecycle
activities.
Implementations of this interface must supply a zero-argument constructor
for use by ActionServlet. Configuration can be accomplished by
providing standard JavaBeans property setter methods, which will all have
been called before the init()
method is invoked.
This interface can be applied to any class, including an Action subclass
