Hi Friends hope everyone knows autocomplete in jquery. It may be difficult for us to implement autocomplete in STRUTS2. Believe me it is as simple as static autocomplete in jquery. I will show you how to implement dynamic (data is coming from oracle) autocomplete in struts2 with the help of JQUERY. JQUERY has many options, method and events, I am not going to explain all these. Please refer  jquery  autocomplete API document(http://api.jqueryui.com/autocomplete/).

Please flow the below steps to achieve the autocomplete in STRUTS2.

Step 1


Create a dynamic web project using eclipse. I have used java1.7 and below jar files to create struts2 project.

Step 2

Create tow jsp files

  1. index.jsp – which will send the request for suggested country

<%@ page contentType=”text/html; charset=UTF-8″ %>
<%@ taglib prefix=”s” uri=”/struts-tags” %>
<style type=”text/css”>
body {
font-family: “Trebuchet MS”, “Helvetica”, “Arial”, “Verdana”, “sans-serif”;
font-size: 62.5%;
<meta charset=”utf-8″>
<title>jQuery UI Autocomplete – Remote JSONP datasource</title>
<link rel=”stylesheet” href=”http://code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css”>
<script src=”http://code.jquery.com/jquery-1.10.2.js”></script>
<script src=”http://code.jquery.com/ui/1.10.4/jquery-ui.js”></script>
.ui-autocomplete-loading {
background: white url(‘images/ui-anim_basic_16x16.gif’) right center no-repeat;
#city { width: 25em; }
<script type=”text/javascript”>
$(function() {

$( “#country”).autocomplete({
// alert(“hi”);
source: function( request, response ) {
// alert(“hi”+request.term);
url: “http://localhost:7001/StrutsAutocomplete/getcountry”,
dataType: “json”,
data: {
name_startsWith: request.term
success: function( data ) {
// alert(“”+data);
response( $.map( data.state, function( item ) {

return {
label: item,
value: item



error: function(XMLHttpRequest, textStatus, errorThrown){
alert(‘error – ‘ +errorThrown);
//console.log(‘error’, textStatus, errorThrown);
minLength: 2
<h1>Struts 2 Autocomplete using jquery and oracle</h1>

<s:form action=”success”>
<s:textfield name=”country” label=”Country Name” id=”country”/>




  1. country.jsp – which will send the JSON response with list of countries.

<%@page import=”java.util.List,org.codehaus.jackson.map.ObjectMapper”%>
<%@page import=”org.codehaus.jackson.JsonGenerationException”%>
ObjectMapper mapper = new ObjectMapper();

List countryList=(List) request.getAttribute(“countyList”);
catch (JsonGenerationException e) {
// TODO Auto-generated catch block
catch (Exception e) {
// TODO Auto-generated catch block




Note- country.jsp do not have any html tag

Step 3

Create two action class – AutoCompleteAction.java and CountryAction.java.

Create one DAO class – CountryDAO.java

Step 1, step 2 and step 3 is very simple, we have just created the STRUTS2 project.

Note – we have used Jackson mapper to make JSON output file.

Step 4

Create a table and insert some country name. check db.sql.


drop table country;

create table country(countryname varchar2(20),countrycode varchar2(5));


insert into country(countryname,countrycode) values(‘Afghanistan’,’93’);

insert into country(countryname,countrycode) values(‘Albania’,’355′);

insert into country(countryname,countrycode) values(‘Algeria’,’213′);

insert into country(countryname,countrycode) values(‘American Samoa’,’1684′);

insert into country(countryname,countrycode) values(‘Andorra’,’376′);

insert into country(countryname,countrycode) values(‘Angola’,’244′);

insert into country(countryname,countrycode) values(‘Anguilla’,’1264′);

insert into country(countryname,countrycode) values(‘Antarctica’,’672′);

insert into country(countryname,countrycode) values(‘India’,’91’);

insert into country(countryname,countrycode) values(‘ndonesia’,’92’);


Step 5

Run the project http://localhost:7001/StrutsAutocomplete/autocomplete

Note – check your struts.xml for your action name.

<?xml version=”1.0″ encoding=”UTF-8″ ?>
“-//Apache Software Foundation//DTD Struts Configuration 2.0//EN”

<constant name=”struts.devMode” value=”true” />
<package name=”default” namespace=”/” extends=”struts-default”>

<action name=”autocomplete”
class=”com.codewale.example.action.AutoCompleteAction” >
<result name=”success”>/pages/index.jsp</result>
<action name=”getcountry”
class=”com.codewale.example.action.CountryAction” >
<result name=”country”>/pages/country.jsp</result>


Step 6

Type al in text box

Hope it is helpful and you will be able to implement in your project.
