Initialize the given binder instance, e.g. with custom editors. Called by BindUtils#bind. This method allows you to register custom editors for certain fields of your command class. For instance, you will be able to transform Date objects into a String pattern and back, in order to allow your JavaBeans to have Date properties and still be able to set and display them in for instance an HTML interface.

Parameters:

request - current request

binder - new binder instance

Throws:

ServletException - in case of invalid state or arguments
