 here is the scenario .  I have a jsp page and i have inluded another jsp  by  <jsp:include page="tba_contacts_data.jsp" flush="true"/>  . i am populating data in this included jsp through ajax and display tag   and   I  am trying to access the elements from this included jsp  by save button on my parent jsp.. i am using request.getParameter() to get elements of included jsp but getting null always. What  i am doing wrong in this..?

1. parent jsp code - 
	<div id="addContactResults">	
	<jsp:include page="tba_contacts_data.jsp" flush="true"/>	
2. included jsp code - 
  	<div id="display_table_results_2" >
 	<div id="blue_table_header_1" style="width:800px" class="header_blue1"><span align="right" class="pagebanner">Collateral Statement</span></div>
    <div  align="left"  style="overflow-y:auto;<%=height%>;width:800px">
                style="<%= height %>;width:800px">
            <display:column   title="<input type='checkbox'  onclick='selectAll(this)'/>" class="centered" style="width:30px">
                <input  type="checkbox"  id="contactId" name="contactId" style="width:30px" class="centered" value="<c:out value='${row.CONTACT_ID}'/>"  >
            <display:column sortable="true" style="width:250px"   title="Contact Name" >
            	<c:out value='${row.CONTACT_NAME}'/>
            	Email : <c:out value='${row.EMAIL_ADDRESS}'/>
javascript code - 
 var arrAccountInput = document.getElementsByName("contactId");
	 var accountCheckList = new Array();
	 var j = 0;
	  var tbaCustomerForm = document.tbaCustomerForm;
	for (i=0; i<arrAccountInput.length; i++)
        if (arrAccountInput[i].checked)
     alert("jcount = "+j);
   // var tbaCustomerform = document.tbaCustomerForm;
    alert("count = "+tbaCustomerForm.count.value);
	tbaCustomerForm.toDo.value = "tba_save_contact_data"; ="edit_customer";
action class code - 
int count  =  customerForm.getCount();
for (int i = 1; i <=count; i++)
   String checkbox1 = request.getParameter("contactId");

Your issue is probably with Javascript, so you should add the Javascript zone for your question.

When you do an include in a JSP file, the contents are included into the page that is returned to the browser client -- the client has no concept that some lines of the resulting HTML came from a different file on the server.  So that fact is not relevant to your problem.

The ajax call is probably not working the way you want.  It might not be executed, it might not be updating the right part of the DOM.  Many things could be wrong.

You should put an alert into the javascript that you think will be executed based on clicking on a button, and go from there.

I assume that your request.getParameter() on the server is getting null because your javascript is not executing correctly to fill in the required parameter.
