That’s your choice how you want to impliment the validation.There are 2 ways which as of now seems feasible to me

1. Client side validation using JavaScript.
2. Server Side validation in your action class.

For the first part your both data-picker must have id and name so once user filled ToDate and FromDate and before submitting the form you can call a java-script function where you can fetch the values of respective date-picker fields using java-script document.getEmelemntById() and can run your comparison logic.

Other option is to let Struts2 fill the ToDate and FromDate values in your action class and you can use validate method inside your Action to perform date validation.choice is all yours.

You can even play around with validation framework even.

Update

After playing around with J query plugin source code here is the workaround we have

 <s:form id="form" theme="xhtml">
    <sj:datepicker id="date12" name="date12" label="With Close Event" onCompleteTopics="onDpClose"/>
    <sj:datepicker id="date13" name="date13" label="With Min and Max Date" minDate="0" maxDate="+2m"/>
    </s:form>

   <script type="text/javascript">
        $.subscribe('onDpClose', function(event,data) {
        $('#date13').datepicker( "option" , 'minDate',event.originalEvent.dateText ); 
     });
   </script> 

In similar way can work for other way around.Hope this will work for you.
