First of all you have to create a Twitter app, hence you have to go to dev.twitter.com and log in with your twitter account
Create my Access tokens
First of all you need the following libraries
common-codec-1.4.jar http://mirrors.ibiblio.org/pub/mirrors/maven2/commons-codec/commons-codec/1.4/commons-codec-1.4.jar
jtwitter.jar http://www.winterwell.com/software/jtwitter/jtwitter.jar
sign-core-1.2.1.1.jar http://code.google.com/p/oauth-signpost/downloads/detail?name=signpost-core-1.2.1.1.jar
Next create a Web application with Netbeans
In the index.jsp set 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>JSP Page</title>
</head>
<body>
<form name="form1" action="NewServlet" method="Post">
User:<input type="textfield" name="user"/><br/>
Message:<input type="textfield" name="message"/><br/>
<input type="submit" value="Enviar"/>
</form>
</body>
</html>
Next create a Servlet. You may call it NewServlet
with the following code:
package com.ejemplo;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import winterwell.jtwitter.OAuthSignpostClient;
import winterwell.jtwitter.Twitter;
public class NewServlet extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String JTWITTER_OAUTH_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxx";
String JTWITTER_OAUTH_SECRET = "XXXXXXXXXXXXXXXXXX";
String JTWITTER_ACCESS_TOKEN = "yyyyyyyyyyyyyyyyyyyyyyyyyy";
String JTWITTER_ACCESS_TOKEN_SECRET = "YYYYYYYYYYYYYYY";
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
out.println("Your Message was sent");
OAuthSignpostClient oauthClient = new OAuthSignpostClient(JTWITTER_OAUTH_KEY, JTWITTER_OAUTH_SECRET, JTWITTER_ACCESS_TOKEN, JTWITTER_ACCESS_TOKEN_SECRET);
Twitter twitter = new Twitter(request.getParameter("user"), oauthClient);
String fecha = (new Date()).toString();
twitter.updateStatus(request.getParameter("message") + fecha);
} catch (Exception ex) {
out.println(ex.getMessage());
ex.printStackTrace();
} finally {
out.close();
}
}
//
/**
* Handles the HTTP
GET method.* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Handles the HTTP
POST method.* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Returns a short description of the servlet.
* @return a String containing servlet description
*/
@Override
public String getServletInfo() {
return "Short description";
}//
}
Replace xxxxx with Consumer key
Replace XXXX with Consumer secret
Replace yyyyy with Access token
Replace YYYY with Access token secret
Finally upload you application to a webserver and run the app
