Javamial : Send mail over SSL
I must send a mail use a SMTP with SSL.
This is an example of my code :
publicvoid sendMail(String destinatario,String mittente,String oggetto,String messaggio,String fileName,String fileNameInMail)throws Exception
{
if (protocol.equals("smtps")){
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
}
props=System.getProperties();
props.setProperty("mail."+protocol+".host", mailServer);
props.setProperty("mail.transport.protocol", protocol);
if (protocol.equals("smtps")){
props.setProperty("mail.smtps.auth","true");
props.setProperty("mail.smtps.starttls.enable","true");
props.setProperty("mail.smtps.socketFactory.fallback","false");
props.setProperty("mail.smtps.socketFactory.class", SSL_FACTORY);
props.setProperty("mail.smtps.socketFactory.port", UtilitaGenerale.getStringa(port));
}
Authenticator auth=null;
if(!mailUser.trim().equals(""))
auth=new MyAuthenticator(mailUser,mailPassword);
boolean debug =false;
//Session session = Session.getInstance(props,auth);
Session session=Session.getInstance(props,auth);
session.setDebug(true);
try{
Message msg =new MimeMessage(session);
Address mit=new InternetAddress(mittente);
msg.setFrom(mit);
InternetAddress[] address ={new InternetAddress(destinatario)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(oggetto);
MimeBodyPart textPart =new MimeBodyPart();
textPart.setContent(messaggio,"text/plain");
MimeBodyPart attachFilePart =new MimeBodyPart();
FileDataSource fds =new FileDataSource(fileName);
attachFilePart.setDataHandler(new DataHandler(fds));
attachFilePart.setFileName(fileNameInMail);
Multipart mp =new MimeMultipart();
mp.addBodyPart(textPart);
mp.addBodyPart(attachFilePart);
msg.setContent(mp);
Transport transportTemp=null;
transportTemp= session.getTransport(protocol);
transportTemp.connect(mailServer,port,mailUser,mailPassword);
transportTemp.send(msg);
transportTemp.close();
}
catch(Exception e)
{
throw e;
}
finally
{
session=null;
}
}
but I obtain this error :
