It has just subject and no content in my inbox receive gmail :
And log :
And my code :
try {
MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
// Set the host smtp address
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.port", SMTP_PORT);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.class", SSL_FACTORY);
props.put("mail.smtp.socketFactory.port", SMTP_PORT);
props.put("mail.smtp.ssl.trust", "*");
props.put("mail.smtp.ssl.socketFactory", sf);
} catch (GeneralSecurityException e) {
e.printStackTrace();
}
.......
.......
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props, auth);
session.setDebug(true);
// create a message
MimeMessage msg = new MimeMessage(session);
msg.setText("UTF8");
// set the from and to address
InternetAddress addressFrom = new InternetAddress(SMTP_AUTH_USER);
msg.setFrom(addressFrom);
System.out.println(addressFrom);
msg.setSubject(subject, "utf-8");
......
......
try {
String content = replaceCharacterInEmail(cus, null,null, message);
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setContent(content, "text/html; charset=utf-8");
// attach the file to the message
Multipart mp = new MimeMultipart();
int count = 0;
if(files != null){
while (count < files.size()) {
MimeBodyPart mbdp = new MimeBodyPart();
mbdp.attachFile(files.get(count));
mp.addBodyPart(mbdp);
count++;
}
}
// create the Multipart and add its parts to it
mp.addBodyPart(mbp1);
// add the Multipart to the message
msg.setContent(mp);
Transport.send(msg);
} catch (Exception e) {
invalidAddress += (", " + address.trim());
e.printStackTrace();
}finally{
if (!"".equals(emailFails)) {
emailFails = emailFails.substring(1);
}
}
But, when i test above code at another project test (java application) with above lib javamail. It's ok :
.
I don't think problem at version of lib javamail. I don't know different between 2 project, because part send email is similar. How can i fix that error ?

Answer 1

Please observe this email structure:
-- multipart/mixed
-- mutlipart/alternative
-- text/plain
-- text/html
-- application/octet-stream (or any other mimetypes)

Answer 2

I found problem is conflict library at lib of jboss server and lib of app.ear (deploy).
