Example: Get Autocomplete Feature In Java/Jsp With jQuery API

jQuery » on Sep 9, 2012 { 58 Comments } By Sivateja

Hi friends, let us see how to get autocomplete effect in normal java/jsp applications, with the help of jQuery. I hope every body knows the importance of using autocomplete feature in java/.net or some other technologies.ย ย  Am going to use jQuery API in order to get this effect into normal jsp to make our life little easier ๐Ÿ™‚ , let us start….

Required Files:

  • index.jsp
  • list.jsp
  • jquery.autocomplete.js
  • jquery-1.4.2.min.js
  • style.css

Web application Directory Structure:


Note:ย  File i used in css,images directories are just for giving little graphical touch ๐Ÿ™‚ if want you can remove them.


<link rel="stylesheet" type="text/css" href="css/style.css" />
<script type="text/javascript" src="JS/jquery-1.4.2.min.js"></script>
<script src="JS/jquery.autocomplete.js"></script>

<font face="verdana" size="2">
<font size="4">Java(jsp)/jQuery Autocompleter Example ::: <font color="#809e02"></font></font>

Select Countryย ย  :
<input type="text" id="country" name="country"/>



<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page import="java.sql.*"%>
<%@page import="java.util.*"%>

     String s[]=null;

     Connection con =DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE","system","admin");
     Statement st=con.createStatement();
     ResultSet rs = st.executeQuery("select * from countries");

       List li = new ArrayList();


       String[] str = new String[li.size()];
       Iterator it = li.iterator();

       int i = 0;
           String p = (String);
           str[i] = p;

    //jQuery related start
       String query = (String)request.getParameter("q");

       int cnt=1;
       for(int j=0;j<str.length;j++)
              if(cnt>=5)// 5=How many results have to show while we are typing(auto suggestions)
    //jQuery related end


catch(Exception e){



.ac_results {
	padding: 0px;
	border: 1px solid #84a10b;
	background-color: #84a10b;
	overflow: hidden;
.ac_results ul {
	width: 100%;
	list-style-position: outside;
	list-style: none;
	padding: 0;
	margin: 0;
.ac_results li {
	margin: 0px;
	padding: 2px 5px;
	cursor: default;
	display: block;
	color: #fff;
	if width will be 100% horizontal scrollbar will apear
	when scroll mode will be used
	/*width: 100%;*/
	font-size: 12px;
	it is very important, if line-height not setted or setted
	in relative units scroll will be broken in firefox
	line-height: 16px;
	overflow: hidden;
.ac_loading {
	background: white url('../images/indicator.gif') right center no-repeat;
.ac_odd {
	background-color: #84a10b;
	color: #ffffff;
.ac_over {
	background-color: #5a6b13;
	color: #ffffff;
	font-family:Arial, Helvetica, sans-serif;
	border:1px solid #84a10b;
	background:white url(../images/search.png) no-repeat 3px 2px;



See in list.jsp line no.33 you may get one doubt, what is that ‘q‘ right ? in fact we are not sending any parameter with name ‘q’ from the input.jsp but for every keyup in the text box (in index.jsp) jquery will sends each character to the list.jsp in the form of ‘q’ and compares with the values in that list, i mean ‘q’ is the default parameter using by jQuery API.

How to send extra parameters along with that q:

$(‘#country’).autocomplete(“list.jsp”, {extraParams: {state: California }} );

This will generates the internal URL like

    Good One Java4s team.nice explanation..:)

  2. Java4s says:


    Thank you ๐Ÿ™‚

  3. Pavan says:

    good example…sir,is their any jquery plugin for automatic session end of an user and logging out if the user is idle for some time…eg banking application…

  4. Java4s says:


    Yeah we can use ‘jQuery Idle Timeout‘ concept, but i don’t encourage this way as being in session is very important for any application, if we use jQuery for sessions its little risky as jQuery depends on browsers some times.

    So always better choice is considering the underlying(in what technology we did the particular application) technology only.
