How to use spring validator with multiaction controller?

Hi, I am trying to use spring validator with multiaction controller.

The configuration is as below- /**/configurationList.do=list /**/configurationUpdate.do=update /**/configurationSave.do=commit

            </value>
        </property>
    </bean>
</property>
<property name="delegate">
    <ref bean="configurationManagementDelegate" />
</property>
<property name="validators" >
    <ref bean="configurationManagementValidator"/>
</property>

<bean id="configurationManagementDelegate" class="in.gov.uidai.web.portal.delegate.ConfigurationManagementDelegate">
</bean>

<!-- Validator class for ConfigurationManagementController -->
<bean id="configurationManagementValidator" class="in.gov.uidai.web.portal.spi.validation.impl.ConfigurationManagementValidator">

And the controller has method called update(..., BindException error)

----it shows error saying BindException class can't be instantiated - .

org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.validation.BindingResult]: Specified class is an interface
