Used to dynamically create instances of Customer Center beans and
drilldowns and provide the ability for customers to override them.
Specify the fully qualified class name for the Class you wish to
create. This method will look through global properties to determine
if that class has been overridden. If overridden, you'll get back
an instance of the customized Class. If not, you'll get back an
instance of the Class you have requested.
The property lookup will use the name of the class passed in with
".subclass" tacked on. So to override the class com.portal.Foo a
customer would create a property entry as follows
com.portal.Foo.subclass=com.mypkg.Bar
Parameters:
className - The class you want to dynamically instantiate
