hi i have to set a int value to a text box but i i am getting different symbols in alert box. my code is

function getID(str1) {
	if (searchReq.readyState == 4 || searchReq.readyState == 0) {
		
    var url='searchbox?Action=check&search=' + str1;
		searchReq.open("GET",url , true);
		searchReq.onreadystatechange = getValue; 
		searchReq.send(null);
	}		
}


function getValue() {
	if (searchReq.readyState == 4) {
   alert(searchReq.responseText)
   document.getElementById('location_sn').value=searchReq.responseText;

    if(!((str.trim()).equals(""))){    
                         
             
              int  eLst=deptDB.selectDepartmentList(str);
             
              System.out.println(eLst);

              response.getWriter().write(eLst);  
             
            }  
            else{  
                System.out.println("Length of string"+("".length()));  
                response.getWriter().write("");  
            }  
    }

Sorry problem is mine. I have to pass Sting or char to write methode..now it's solved

response.getWriter().write(String.valueof(eLst));
