Refresh / Reload Div Without Reloading Page

Hi,

I have a div on a page which I would like to refresh/load on a timer, say every 5 mins using java, is this possible?  If so, any help would be greatly appreciated :)

I've attached the div.

<div id="DiaryNotice" style="position:absolute; top:0px; left:200px; width:1000px; font-size:63px; font-weight:bold; color:#ED9336; cursor:default;">
       	  <% strSQL = "Select * From [Diary Action Home] WHERE [Diary FAO] = '" & Replace(session("Name"),"'","''") & "';"
		  		objRS2.Open strSQL, objConn
					If Not objRS2.EOF Then%>		  
        				<marquee style="cursor:pointer;" onClick="window.open('Diary.asp?SourceTable=Diary Action Home');"> You have diary records overdue - click here to view...</marquee>
                    <%End If%>
               <%objRS2.Close%>
         </div>
