problem with calendar display(new to struts) using struts

[shilpa thakare]

I am having different UI components in my jsp page.
I have used one calendar control displayed using javascript.

Now, when any validation error occurs (using Validator framework for struts), the calendar popup is not visible until we reload the page.
I want the calendar to be clickable and the date to be entered without reloading the page

My struts-config.xml looks something like this::

<action path="/assigntask"
type="AssignTaskAction"
name="assingTaskForm" scope="request" input="/jsp/assigntask.jsp" >
<forward name="success" path="/jsp/Success.jsp" />
<forward name="failure" path="/jsp/error.jsp" />
</action>

The assigntask.jsp contains the calendar control.

I have heard about struts-layout. Downloaded its jar file
but I am not getting the exact steps to be followed.

Can anyone help me with this...
or either the exact steps and details for using struts-layout
as I have just started working on struts....

Plzzzzz.give me the right path...thanks in advance
