Called from
#init() to create the
ObjectWrapper; to customzie this aspect, in most cases you
should override
#createDefaultObjectWrapper() instead. Overriding this method is necessary when you want
to customize how the
ObjectWrapper is created
from the init-param values, or you want to do some
post-processing (like checking) on the created
ObjectWrapper. To customize init-param interpretation,
call
#getInitParameter(String) with
Configurable#OBJECT_WRAPPER_KEY as argument, and see if it
returns a value that you want to interpret yourself. If was
null or you don't want to interpret the
value, fall back to the super method.
The default implementation interprets the
object_wrapper servlet init-param with
calling
Configurable#setSetting(String,String) (see valid values there), or if there's no such servlet
init-param, then it calls
#createDefaultObjectWrapper().
