Here is the code which i got from internet but it is not sending email!
This is my servlet code

import java.io.*;
import java.text.*;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.servlet.http.*;
import javax.servlet.*;

public class SendMailServlet extends HttpServlet {
private String mMailServer;
private DateFormat mDateFormat;

public void init() {
mMailServer = "localhost";
}

public void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {

String user="user";
String pwd="pass";

BufferedReader in = request.getReader();

String address = in.readLine();

StringBuffer content = new StringBuffer();
String line = null;
while ((line = in.readLine()) != null) {
content.append(line);
content.append('\n');
}

String message = "100 ok";

try {
sendMail(mMailServer,user,pwd, address, content.toString());
} catch (Throwable t) {
message = "200 " + t.toString();
}
response.setContentType("text/plain");
response.setContentLength(message.length());
PrintWriter out = response.getWriter();
out.println(message);
out.flush();
}

/* This method form Mail and send to server*/
private void sendMail(String server, String user,
String pwd, String address, String content) throws Exception {

Properties p = new Properties();
p.put("local host", server);
Session s = Session.getDefaultInstance(p, null);
InternetAddress from = new InternetAddress(user);
InternetAddress to = new InternetAddress(address);
MimeMessage m = new MimeMessage(s);
m.setFrom(from);
m.addRecipient(Message.RecipientType.TO, to);

m.setSubject("Mail from [" + from + "]");
m.setText(content.toString());
Transport.send(m);
}

}
