Example 1 with CommunicationsException

use of net.java.sipmack.sip.CommunicationsException in project Spark by igniterealtime.

the class MessageProcessing method sendMessage.

/**
 * Sends an instant message in pager-mode using a SIMPLE/SIP MESSAGE
 * request. In pager-mode, each message is independent of any other
 * messages. An instant message will be the body of the MESSAGE request to
 * be sent, therefore, its format must conform to the values in the
 * "Content-Type" and "Content-Encoding" header fields. Refer to Message for
 * details.
 *
 * @param to              the address of receiver.
 * @param messageBody     the message to be sent. The messageBody will be the body of
 *                        the MESSAGE request to be sent and its format must conform to
 *                        the values in the parameters contentType and contentEncoding.
 *                        Please refer to the setBody method for details.
 * @param contentType     the Internet media type of the messageBody. Please refer to
 *                        the Message.setBody method for details.
 * @param contentEncoding the encodings that have been applied to the messageBody in
 *                        addition to those specified by contentType. Please refer to
 *                        the Message.setBody method for details.
 * @return the transaction ID associated with the MESSAGE request sent by
 *         this method.
 * @throws CommunicationsException
