hi friend,

For this you can create a html page where you put a textbox and a submit button inside the form tag and write a Servlet for processing the redirect operation. In Servlet get the text what is entered into the textbox at html page then create a String with the value of google search page url and textbox value. And then pass this newly created String as the argument of sendRedirect() method.

An example is as follows : HTML page index.html is as follows :

    <p><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 <br>
Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><br>
<html><br>
<head> <br>
<title>Google Search</title><br>
</head><br>
<body><br>
<form method="get" action="
GoogleSearch"><br>
<table><br>
<tr><br>
<td>Google Search </td><br>
<td><input type="text" 
name="search"/></td><br>
<td><input type="submit" 
value="search"/></td><br>
</tr><br>
</table><br>
</form><br>
</body><br>
</html></p>

And you can write the Servlet as follows :

package net.roseindia;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public class GoogleSearch extends HttpServlet {

protected void doGet(HttpServletRequest request, 
HttpServletResponse response) throws ServletException, IOException {

String text = request.getParameter("search");
if(!((text) == null))
{
String url = 
"http://www.google.com/#hl=en&tbo=d&site=&source=hp&q="+text;
response.sendRedirect(url);
}
} 
protected void doPost(HttpServletRequest request, 
HttpServletResponse response) throws ServletException, IOException {
doGet(request, response);
}

}

And the web.xml can be written as follows :

    <?xml version="1.0" encoding="UTF-8"?><br>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" <br>
xmlns="http://java.sun.com/xml/ns/javaee" <br>
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" <br>
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" <br>
id="WebApp_ID" version="3.0"><br>
<display-name>googleSearch</display-name><br>
<welcome-file-list><br>
<welcome-file>index.html</welcome-file> <br>
</welcome-file-list><br>
<servlet><br>
<servlet-name>GoogleSearch</servlet-name><br>
<servlet-class>net.roseindia.GoogleSearch</servlet-class><br>
</servlet><br>
<servlet-mapping><br>
<servlet-name>GoogleSearch</servlet-name><br>
<url-pattern>/GoogleSearch</url-pattern><br>
</servlet-mapping><br>
</web-app><br>
