Reply to a message

Add the recipients. 1. Invoke Message.addRecipients() and provide the type of recipient (TO, CC, or BCC) and

the array of addresses to add as parameters to the method. If the message has multiple types of

recipients, invoke

addRecipients() once for each recipient type.

msg.addRecipients(Message.RecipientType.TO, toList);

Specify the name and email address of

the sender.

Address from = new Address("scott.mcph[email protected]", "Scott

McPherson");

msg.setFrom(from);

Add a subject line. >Invoke setSubject(String).

msg.setSubject("Test Message");

Specify the message contents. >Invoke setContent(String). Typically, the application retrieves content from text that a

BlackBerry® device user types in a field.

try {

msg.setContent("This is a test message.");

} catch(MessagingException e) {

System.out.println(e.getMessage());

}

Send the message. >Invoke Transport.send(Message). The Transport object represents the messaging

transport protocol.

} catch(MessagingException e) {

System.out.println(e.getMessage());
