What is the use of set-property element . It is supported by most all of the elements
that define Struts entities such as form-bean, action-mapping, action,
and plug-in.
I cam across this :All set-property elements for a given plug-in will be processed prior to calling theplug-in’s init( ) method. This allows the plug-in to use the value of the properties in
the init( ) method.
