Error in sending mail (mail exception error)

Question

HI guys,
I used smtp method to send mail in the java application. If i am trying through outlook it's working. but if i used in the application it's throwing this error. can anyone help me?
I am using SMTP
(org.springframework.mail.javamail) method to send the mail.
below is the code i used to implement this,
JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
MailDO mailDO = new MailDO();
mailDO.setTo(To_email);
mailDO.setFrom(From_email);
mailDO.setCc(Cc_email);
mailDO.setSubject(Subject);
Properties prop = new Properties();
prop.put("mail.smtp.auth", "true");
mailSender.setHost("smtp.domain.co.in");
mailSender.setUsername("[email protected]");
mailSender.setPassword("password");
mailSender.setProtocol("smtp");
mailSender.setPort(25);
mailSender.setJavaMailProperties(prop);
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message);
helper.setFrom(mailDO.getFrom());
helper.setCc(ccAddColl);
helper.setSubject(mailDO.getSubject());
helper.setTo(mailDO.getTo());
helper.setText(mailDO.getBody(),true);
try{
mailSender.send(message);
catch(MailException ex) {
System.err.println(ex.getMessage());
ex.printStackTrace();
But i am getting following error :-
Mail server connection failed; nested exception is javax.mail.NoSuchProviderException: smtp
org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.NoSuchProviderException: smtp
javax.mail.NoSuchProviderException: smtp

Answer 1

I do not know org.springframework.mail.javamail but if it is a framework, a wrapper around a mail provider, like the standard JavaMail one, the latter must be on the classpath too and maybe it must be registered somehow.
But it is just a guess - I don't know the stuff.
