    // recipient's email id needs mentioned.     string = "fredxya@gmail.com";      // sender's email id needs mentioned     string = "johnxyzn@gmail.com";      properties props = new properties();     props.put("mail.smtp.host", "smtp.gmail.com");     props.put("mail.smtp.socketfactory.port", "465");     props.put("mail.smtp.socketfactory.class",             "javax.net.ssl.sslsocketfactory");     props.put("mail.smtp.auth", "true");     props.put("mail.smtp.port", "465");      session session = session.getdefaultinstance(props,         new javax.mail.authenticator() {             protected passwordauthentication getpasswordauthentication() {             return new passwordauthentication("fredxyz@gmail.com","password");             }         });      try{         // create default mimemessage object.         mimemessage message = new mimemessage(session);          // set from: header field of header.         message.setfrom(new internetaddress(from));          // set to: header field of header.         message.addrecipient(message.recipienttype.to,                   new internetaddress(to));          // set subject: header field         message.setsubject("test subject");          // set actual message         message.settext("this test");          // send message         transport.send(message);         system.out.println("sent message successfully....");     }catch (messagingexception mex) {         system.out.println (mex) ;         mex.printstacktrace();     }

issue was using 2 step verification in gmail. solution use application specific password (asp): https://accounts.google.com/issuedauthsubtokens?hide_authsub=1
