Interface PlugIn
- All Known Implementing Classes:
ValidatorPlugIn
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.
