Validation on start date and end date .

Question

Hi every body ,
Hi have a problem on validation on the start date & end date problem.
I have taken two *<h:inputText>* & one *<t:commandLink>* controls.When I am clicking on the <t:commandLink> control I want to validate that end date should greater than start date .Could any body help me out from this problem .
Here is my code :
<rich:dataTable id="dataTable" 
                           value="#{adminBacking.dataModel}"
                           var="item">
   <h:column>
     <f:facet name="header">
          <h:outputText value="Start Date" />
     </f:facet>
     <h:inputText size="11" id="startDate" value="#{item.startDate}" onclick="showCalendarControl(this);" />                      </h:column>
<h:column >
     <f:facet name="header">
          <h:outputText value="End Date" />
     </f:facet>
     <h:inputText size="11" id="endDate" value="#{item.endDate}" onclick="showCalendarControl(this);" />
</h:column>
<h:column>
     <f:facet name="header">
          <h:outputText value="Update Row" />
     </f:facet>
     <t:commandLink id="update" action="#{adminBacking.updateEvent}"  value="Update" />     
</h:column>
</rich:dataTable>**Here I am taking the date by a simple date picker in the start date & end date field.
Thanks ,
sb
