Exception while sending email from a Servlet

[Alex Marks]

I am using a Servlet with to send a email. But i faced a error while sending email. Here is the code:
...
Properties props = new Properties();
props.setProperty("mail.transport.protocol","smtp");
props.setProperty("mail.host","smtp.gmail.com");
props.setProperty("mail.user","abc");
props.setProperty("mail.password","abc");
Session mailSession = Session.getDefaultInstance(props,null);
Transport transport = mailSession.getTransport();

MimeMessage message = new MimeMessage(mailSession);
message.setContent("This is a test","text/plain");
message.addRecipient(Message.RecipientType.TO,new InternetAddress("[e-mail]"));
transport.connect();
transport.sendMessage(message,message.getRecipients(Message.RecipientType.TO));
transport.close();
...

The error i get is : javax.mail.MessagingException: 530 5.7.0 Must issue a STARTTLS command first 38sm1046192nzk

Thank you for your help and looking for your replies.

Try adding

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

Alex,

Try using, Apache Commons Email 1.0. This works on J2EE 1.4 and upwards. This API is built on top of Sun's Java Mail. It is simpler than Java Mail.

It is as simple as writing and executing the following code.

SimpleEmail email = new SimpleEmail();
email.setHostName("mail.myserver.com");
email.addTo("[e-mail]", "John Doe");
email.setFrom("[e-mail]", "Me");
email.setSubject("Test message");
email.setMsg("This is a simple test of commons-email");
email.send();


Hope this helps.

Regards
Santosh

The Commons Email jar can be downloaded from http://jakarta.apache.org/site/downloads/downloads_commons-email.cgi.

Examples using the Commons Email jar can be found at http://jakarta.apache.org/commons/email/examples.html.

Best of luck.

Thank you very much for your advices.
I have tried to search throught Internet, I manage to find the code to send Email with SSL. However I encounter problem. Here is the code.
public class SendingEmail {
private static final String SMTP_HOST_NAME = "smtp.gmail.com";
private static final String SMTP_PORT = "465";
private static final String emailMsgTxt = "Test Message Contents";
private static final String emailSubjectTxt = "A test from gmail";
private static final String emailFromAddress = "[e-mail]";
private static final String SSL_FACTORY "javax.net.ssl.SSLSocketFactory";
private static final String[] sendTo = { "[e-mail]"};

public static void main(String args[]) throws Exception {

Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

new SendingEmail().sendSSLMessage(sendTo, emailSubjectTxt,
emailMsgTxt, emailFromAddress);
System.out.println("Sucessfully Sent mail to All Users");
}

public void sendSSLMessage(String recipients[], String subject,
String message, String from) throws MessagingException {
boolean debug = true;

Properties props = new Properties();
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", SMTP_PORT);
props.put("mail.smtp.socketFactory.port", SMTP_PORT);
props.put("mail.smtp.socketFactory.class", SSL_FACTORY);
props.put("mail.smtp.socketFactory.fallback", "false");

Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {

protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("[e-mail]", "123456");
}
});

session.setDebug(debug);

Message msg = new MimeMessage(session);
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);

InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++) {
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);

// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
--------------------------------------------------------------------
The error is : Credentials Rejected.
Please help me to solve this problem ! thank you ! forgive me if this thread is not related to Servlets.

I guess you would need to verify if the SMTP_HOST_NAME and SMTP_PORT are correct.

[Alex Marks]

Annie Smith, actually the code above I copy from the Internet and modify, but someone can use it,someone cannot use it,i am the one cannot use ! really dont understand why it cause error !
Hope to get helps from others ! thank you very much !

Hi
Use this code
Properties props = new Properties();
props.put("mail.smtp.host","111.111.111.111");
session = Session.getDefaultInstance(props, null);
message = new MimeMessage(session);
message.setContent(strMessage, "text/html");
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
message.setSubject(strSubject);
Transport.send(message);


to send email..

In order the above code to work fine, u need to have
mailapi.jar
naming.jar
activation.jar
messagingClient.jar

i am not sure about all of them but let me know if you are facing the problem using the above code

[Makarand Parab]

Hi
you also need to have pop3.jar.
