アプリエンジンメールサービスを使用していますが、添付ファイルを含むメールは送信できません。上記は、メールハンドラと私が得る例外を実装するコードです。 Transport.send（msg）メソッドを使用してメッセージを送信しようとしているときに例外が発生します。添付ファイル付きのメールを送信できません - Googleアプリエンジン
Mail.java
public class Mail {
private Properties props;
private Session session;
private Message msg;
public Mail() {
props = new Properties();
session = Session.getDefaultInstance(props, null);
msg = new MimeMessage(session);
}
public void sendMail(String subject, String msgBody, String recipient,
String recipientName) {
try {
msg.setFrom(new InternetAddress("[email protected]", "Sourcebay"));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(
recipient, recipientName));
msg.setSubject(subject);
msg.setText(msgBody);
Transport.send(msg);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void sendMimeMessage(String subject, String msgBody,
String recipient, String recipientName, byte[] attachment,
BlobInfo blobInfo) {
try {
Multipart mp = new MimeMultipart();
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(msgBody, "text/html");
mp.addBodyPart(htmlPart);
MimeBodyPart attachmentPart = new MimeBodyPart();
attachmentPart.setFileName(blobInfo.getFilename());
attachmentPart.setContent(attachment, blobInfo.getContentType());
mp.addBodyPart(attachmentPart);
msg.setContent(mp);
msg.setFrom(new InternetAddress("[email protected]", "Sourcebay"));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(
recipient, recipientName));
Transport.send(msg);
