Method Detail

• send

  public static void send(Message msg)
                   throws MessagingException

  Send a message. The message will be sent to all recipient addresses specified in the message (as returned from the Message method getAllRecipients), using message transports appropriate to each address. The send method calls the saveChanges method on the message before sending it.

  If any of the recipient addresses is detected to be invalid by the Transport during message submission, a SendFailedException is thrown. Clients can get more detail about the failure by examining the exception. Whether or not the message is still sent successfully to any valid addresses depends on the Transport implementation. See SendFailedException for more details. Note also that success does not imply that the message was delivered to the ultimate recipient, as failures may occur in later stages of delivery. Once a Transport accepts a message for delivery to a recipient, failures that occur later should be reported to the user via another mechanism, such as returning the undeliverable message.

  In typical usage, a SendFailedException reflects an error detected by the server. The details of the SendFailedException will usually contain the error message from the server (such as an SMTP error message). An address may be detected as invalid for a variety of reasons - the address may not exist, the address may have invalid syntax, the address may have exceeded its quota, etc.

  Note that send is a static method that creates and manages its own connection. Any connection associated with any Transport instance used to invoke this method is ignored and not used. This method should only be invoked using the form Transport.send(msg);, and should never be invoked using an instance variable.

  Parameters:

  msg - the message to send

  Throws:

  SendFailedException - if the message could not be sent to some or any of the recipients.

  MessagingException

• send

  public static void send(Message msg,
                          Address[] addresses)
                   throws MessagingException

  Send the message to the specified addresses, ignoring any recipients specified in the message itself. The send method calls the saveChanges method on the message before sending it.

  Parameters:

  msg - the message to send

  addresses - the addresses to which to send the message

  Throws:

  SendFailedException - if the message could not be sent to some or any of the recipients.

  MessagingException

• send

  public static void send(Message msg,
                          String user,
                          String password)
                   throws MessagingException

  Send a message. The message will be sent to all recipient addresses specified in the message (as returned from the Message method getAllRecipients). The send method calls the saveChanges method on the message before sending it.

  Use the specified user name and password to authenticate to the mail server.

  Parameters:

  msg - the message to send

  user - the user name

  password - this user's password

  Throws:

  SendFailedException - if the message could not be sent to some or any of the recipients.

• send

  public static void send(Message msg,
                          Address[] addresses,
                          String user,
                          String password)
                   throws MessagingException

  Send the message to the specified addresses, ignoring any recipients specified in the message itself. The send method calls the saveChanges method on the message before sending it.

  Use the specified user name and password to authenticate to the mail server.

  Parameters:

  msg - the message to send

  addresses - the addresses to which to send the message

  user - the user name

  password - this user's password

  Throws:

  SendFailedException - if the message could not be sent to some or any of the recipients.

• sendMessage

  public abstract void sendMessage(Message msg,
                                   Address[] addresses)
                            throws MessagingException

  Send the Message to the specified list of addresses. An appropriate TransportEvent indicating the delivery status is delivered to any TransportListener registered on this Transport. Also, if any of the addresses is invalid, a SendFailedException is thrown. Whether or not the message is still sent succesfully to any valid addresses depends on the Transport implementation.

  Unlike the static send method, the sendMessage method does not call the saveChanges method on the message; the caller should do so.

  Parameters:

  msg - The Message to be sent

  addresses - array of addresses to send this message to

  Throws:

  SendFailedException - if the send failed because of invalid addresses.

  MessagingException - if the connection is dead or not in the connected state

• addTransportListener

  public void addTransportListener(TransportListener l)

  Add a listener for Transport events.

  The default implementation provided here adds this listener to an internal list of TransportListeners.

  Parameters:

  l - the Listener for Transport events

  See Also:

  TransportEvent

• removeTransportListener

  public void removeTransportListener(TransportListener l)

  Remove a listener for Transport events.

  The default implementation provided here removes this listener from the internal list of TransportListeners.

  Parameters:

  l - the listener

  addTransportListener(javax.mail.event.TransportListener)

• notifyTransportListeners

  protected void notifyTransportListeners(int type,
                                          Address[] validSent,
                                          Address[] validUnsent,
                                          Address[] invalid,
                                          Message msg)

  Notify all TransportListeners. Transport implementations are expected to use this method to broadcast TransportEvents.

  The provided default implementation queues the event into an internal event queue. An event dispatcher thread dequeues events from the queue and dispatches them to the registered TransportListeners. Note that the event dispatching occurs in a separate thread, thus avoiding potential deadlock problems.
