I also want to add that i use Netbeans IDE and Apache Server and i've added all the jar files needed for it, but still i'm getting Exception and ends with "Unable to send". So i'm confused where i made the mistake ?

props.put("mail.smtp.starttls.enable", "true");

you enabled tls but in fact you use ssl (port 465). Try this:

Session mailSession = Session.getInstance(System.getProperties());
        Transport transport = new SMTPTransport(mailSession, new URLName("smtp.gmail.com"));
        transport = mailSession.getTransport("smtps");
        transport.connect("smtp.gmail.com", 465, "[email protected]", "Your-Password-Here");
        MimeMessage m = new MimeMessage(mailSession);
        m.setFrom(new InternetAddress("[email protected]"));
        Address[] toAddr = new InternetAddress[]{ new InternetAddress("to@[email protected]") };
        m.setRecipients(javax.mail.Message.RecipientType.TO, toAddr);
        m.setSubject("set subject if you wish");
        m.setSentDate(new java.util.Date());
        String text = "BODY OF EMAIL";
        m.setContent(text, "text/plain");
        transport.sendMessage(m, m.getAllRecipients());
        transport.close();
       } catch (Exception e) {
           out.println(e.getMessage() + " - " + e.toString());
           e.printStackTrace();

       }

An error occurred at line: 74 in the jsp file: /mailJSP.jsp

The local variable result may not have been initialized

String result = new String();

initialize the variable

For the second exception

private final String SSL_FACTORY  =  "javax.net.ssl.SSLSocketFactory";
int port = 465;
if ("smtp.gmail.com".equals(host)) {
    props.setProperty("mail.smtp.socketFactory.class",SSL_FACTORY);
    props.setProperty("mail.smtp.socketFactory.fallback","false");
    props.setProperty("mail.smtp.socketFactory.port",String.valueOf(port));
  }

This might help you. Worked for me! Also, you should have showed the Stack Trace. It helps to get a better understanding if something unusually has gone wrong with your program.
