Google Map Web Service With JSP

This demo application will show you how to use google map web service for searching any location.

First of all we need to create an Java Web Application with any name, let it be google_app here using Netbeans IDE.
It will create an index.js page.

The code inside the index.jsp will be similar to this

<%--
Document   : index
Created on : 9 Aug, 2012, 12:24:02 PM
Author     : hareramr
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Google Map Demo App</title>
</head>
<body>
<h1>Hello World!</h1>
</body>
</html>

Then we need to click on Services tab and it will look like the image below.

google app

 

 

Then drag the getGoogleMap into index.jsp file. The page will contain the following code

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Google Map Demo App</title>
</head>
<body>
<h1>Hello World!</h1>
<%@ page import="org.netbeans.saas.*, org.netbeans.saas.google.*" %>

<%

try {
String address = “16 Network Circle, Menlo Park”;
java.lang.Integer zoom = 15;
String iframe = “false”;

RestResponse result = GoogleMapService.getGoogleMap(address, zoom, iframe);
//TODO – Uncomment the print Statement below to print result.
//out.println(“The SaasService returned: “+result.getDataAsString());
} catch (Exception ex) {
ex.printStackTrace();
}

%>

</body>
</html>

GoogleMapService.getGoogleMap Method is the  method responsible for getting the location in map. Method
getGoogleMap has three parameter which are address,zoom and iframe.

address – address string to generate map for.
Zoom – level of zoom

We need to change the above code to get loaction search functionality using google map web service.

Before running the application we need the Google api key. After getting the api key ,set the key in
googlemapservice.properties file .

Now the application is ready for searching the location.
So here the first result for “India Gate”

resultgmap
