Question

我正在使用Java Mail API以pdf作为附件发送邮件。请参阅下面的代码

Session session = Session.getInstance(props,
        new javax.mail.Authenticator() {  
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
            }
        }
);   
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(username));

System.out.println(toUserEmails);
for(int i = 0 ; i < toUserEmails.length() ; i++){
    String email = toUserEmails.optString(i);            
    message.addRecipients(
           Message.RecipientType.TO,InternetAddress.parse(email));
}


for(int i = 0 ; i < ccUserEmails.length() ; i++){
    String email = ccUserEmails.optString(i);
    message.addRecipient(Message.RecipientType.CC,new 
        InternetAddress(email));
}

message.setSubject(subject);   
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(body);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();


 if(!attachment.equals("") && attachment != null){
        System.out.println("attachment base64 is " + attachment);                
        byte[] attach = Base64.decodeBase64(new 
                 String(attachment).getBytes("UTF-8"));

        JSONObject mimeTypes = new JSONObject().put("pdf", 
                              "application/pdf");

        System.out.println(attachmentName);
        String ext = attachmentName.split("\\.")[1];
        DataSource source = new 
                   ByteArrayDataSource(attach,mimeTypes.getString(ext));                
        messageBodyPart.setDataHandler(new DataHandler(source));
        messageBodyPart.setFileName(attachmentName);
        multipart.addBodyPart(messageBodyPart);
}
message.setContent(multipart);

Transport.send(message);

它在我的本地机器（窗口8）中工作正常。但由于某些原因，当我在ubuntu上的服务器上部署此代码时，邮件将被发送，而不是任何正文，甚至是文本。和一个名为＆＃34; noname＆＃34;的无效文件正在接近。

我尝试重新启动服务器，更改jar文件版本并稍微更改了代码但没有任何效果。

我无法在stackoverflow上找到任何内容。我正在IBM Websphere Application服务器Liberty上部署war文件。任何人都可以帮助我吗？
