Field Detail


public Logger logger
Logger object to be used to monitor the protocol interactions.
Default null value means no logging. Therefore, to activate logging you should provide a logging object. Example:
 TapSender sender = new TapSender( cx, "" ); 
 sender.logger = Logger.getLogger("com.java4less.sms.tap");
 sender.logger.setLevel( 7 );

Constructor Detail


public TapSender(CommConnector connector,
                 java.lang.String password)
connector - Communitactions Connector that will be used to connect to the SMSC. Usually it's a modem connection but it could be also a direct serial connection or any other, as long as it allows to reach an SMSC that "talks" TAP.
password - TAP password. It will ve provided by the company that offers the TAP gateway. Very often is omitted, just use an empty string in such case.
Method Detail


public boolean sendOneMessage(SmsMessage message)
Sends One Message (high level method).
Simplified method, opens & closes connection to the SMSC/TAP server, catches exceptions and updates message status.
This method is intended mainly for testing purposes. You will usually prefer to send more than one message per connection using sendMessageList


public boolean sendMessageList(java.util.ArrayList mlist)
Send a number of messages (high level method).
Updates each message status. You should check it to know if a particular message was accepted or not.

mlist - To use this method you should first prepare an ArrayList of SmsMessage objects.
true if everything worked normally.
false if any exception was detected.


public boolean open()
             throws TapException,
Opens Communication Connexion and performs initial TAP protocol steps (logon).
If no exception is thrown, you can start sending messages by calling sendMessage.



public boolean sendMessage(SmsMessage m)
                    throws TapException,
Sends an SMS Message (low level method). Requires a previous successful call to open().
if no exception is thrown, updates message status to ACCEPTED or REJECTED.
You can subsequently call this method again to send any number of messages, then call close() when you have finished.

true if message was accepted.


public void close()
           throws BadCloseException
Ends the TAP transaction.
Performs the TAP termination steps and closes the communication channel.
it throws a BadCloseException in two cases :
- during the termination phase the server sent an RS control character that means that it now rejects some messages that it had accepted.
- the termination phase couldn't be performed so we don't have confirmation that the previous case doesn't apply.
