Datepicker does not read the input

Hi, My datepicker is showing up. But when submit is done, it does not read any value from input field.
 
I am using JSP and struts. Any help please
 
[code]
.....
< SCRIPT type = text/javascript >
$( function () {
$( "#datepicker" ).datepicker();
} );
</ SCRIPT >

< P > Date: < INPUT TYPE = "TEXT" property = "holidayDate" id = "datepicker" /></ P >
....
