If you allow me  it works fine also for multi-attachments  the 1st above answer of NINCOMPOOP  with just a little modification like follows     DataSource source source2 source3 source4         source   new FileDataSource myfile     messageBodyPart setDataHandler new DataHandler source      messageBodyPart setFileName myfile     multipart addBodyPart messageBodyPart      source2   new FileDataSource myfile2     messageBodyPart setDataHandler new DataHandler source2      messageBodyPart setFileName myfile2     multipart addBodyPart messageBodyPart      source3   new FileDataSource myfile3     messageBodyPart setDataHandler new DataHandler source3      messageBodyPart setFileName myfile3     multipart addBodyPart messageBodyPart      source4   new FileDataSource myfile4     messageBodyPart setDataHandler new DataHandler source4      messageBodyPart setFileName myfile4     multipart addBodyPart messageBodyPart           message setContent multipart

For an unknow reason  the accepted answer partially works when I send email to my gmail address  I have the attachement but not the text of the email   If you want both attachment and text try this based on the accepted answer        Properties props   new java util Properties        props put  mail smtp host    yourHost        props put  mail smtp port    yourHostPort        props put  mail smtp auth    true                     props put  mail smtp starttls enable    true             Session session   Session getDefaultInstance props  null       Session session   Session getInstance props                new javax mail Authenticator                     protected PasswordAuthentication getPasswordAuthentication                         return new PasswordAuthentication  user    password                                              Message msg   new MimeMessage session       try           msg setFrom new InternetAddress mailFrom            msg setRecipient Message RecipientType TO  new InternetAddress mailTo            msg setSubject  your subject             Multipart multipart   new MimeMultipart             MimeBodyPart textBodyPart   new MimeBodyPart            textBodyPart setText  your text             MimeBodyPart attachmentBodyPart  new MimeBodyPart            DataSource source   new FileDataSource attachementPath      ex    C   test pdf          attachmentBodyPart setDataHandler new DataHandler source            attachmentBodyPart setFileName fileName      ex    test pdf           multipart addBodyPart textBodyPart       add the text part         multipart addBodyPart attachmentBodyPart      add the attachement part          msg setContent multipart             Transport send msg         catch  MessagingException e            LOGGER log Level SEVERE  Error while sending email  e             Update    If you want to send a mail as an html content formated you have to do      MimeBodyPart textBodyPart   new MimeBodyPart        textBodyPart setContent content   text html      So basically setText is for raw text and will be well display on every server email including gmail  setContent is more for an html template and if you content is formatted as html it will maybe also works in gmail
