Class Smpp

java.lang.Object

  +--ipworks.Smpp

public class Smpp

extends java.lang.Object

The Smpp bean implements a lightweight message transmission interface using the Short Message Peer-to-Peer protocol, most known for its use in cellular text messaging.

The Smpp bean will bind as a transceiver, and thus can send and receive messages from the server. Additionally, it can send single and multi-recipient messages, and can upload data.

Using Smpp is quite easy. First, simply set the SMPPServer , SMPPPort , and, if needed, the SMPPVersion properties. Second, a single call to the Connect method with a specified user id and password will connect the bean.

Transmitting messages is just as easy. You can manipulate the Recipients collection directly, or just use AddRecipient method to add recipients one-by-one to the recipient list. After all recipients have been added, a single call to the SendMessage method will transmit the specified message. If the send is successful, the method will set and return the value of the MessageId property. Otherwise, an Error event will fire for each unsuccessful message destination.

The Smpp bean supports message and data transmission, as well as auxiliary operations such as CheckMessageStatus and ReplaceMessage . All non-implemented features of the protocol are supported through the SendCommand method and PITrail event. Due to the nature of the protocol, all methods and operations are implemented synchronously.

IPWorksException

getSMPPVersion

public int getSMPPVersion()

This is the SMPP version to be used throughout the connection.

Currently, the most widely used version of the SMPP protocol is version 3.4. However, since the newest version is 5.0, the default value for the bean is smppVersion50 (0). The value is used by the bean when binding to the SMPPServer to indicate to the server which version of the protocol to use when interpreting commands received from the bean.

Changing the value will not limit the functionality of the bean when performing any operation, as each version of SMPP is backward compatible with previous implementations. However, if the SMPPServer does not recognize a particular command, it will respond with an error indicating that the PDU was erred. Which commands are recognizable is strictly dependent on the implementation of the server, and the adherence to protocol guidelines of that implementation.

setSMPPVersion

public void setSMPPVersion(int SMPPVersion)
                    throws IPWorksException

IPWorksException

getTimeout

public int getTimeout()

A timeout for the bean.

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion, or an error condition is encountered.

If Timeout is set to a positive value, the bean will wait for the operation to complete before returning control.

The bean will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the bean throws an IPWorksException raises an IPWorksException exception .

Please note that by default, all timeouts are inactivity timeouts , i.e. the timeout period is extended by Timeout seconds when data is successfully sent or received.

Optionally, the behaviour of the bean may be changed to absolute timeouts , i.e. the bean will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by theAbsoluteTimeoutconfiguration setting.

The default value for the Timeout property is 60 (seconds).

setTimeout

public void setTimeout(int timeout)
                throws IPWorksException

A timeout for the bean.

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion, or an error condition is encountered.

If Timeout is set to a positive value, the bean will wait for the operation to complete before returning control.

The bean will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

                         java.lang.String recipientAddress)
                  throws IPWorksException

This method will add a recipient of the specified type to the recipient list.

For normal-type recipients, the addresses should be either a dotted IPv4 address (for sending messages to other SMS-enabled applications) or the directory number of a mobile phone. For sending messages to distributed lists, the name of the list should be used.

IPWorksException

cancelMessage

public void cancelMessage(java.lang.String messageId)
                   throws IPWorksException

This method will cancel the specified message.

The CancelMessage method will cancel the message stored on the SMPPServer under the value in MessageId .

IPWorksException

checkLink

public void checkLink()
               throws IPWorksException

This method will check the connection to the server.

The check link operation is mostly used to ensure that the host on the other end of the connection is still active, or that it is still available. While a socket connection may still be available between the client and server, the SMS application on the server may have been taken offline without releasing the socket, or the CPU may be bogged down, etc. The CheckLink method will send a PDU to the server and wait the length of Timeout for a response.

IPWorksException

checkMessageStatus

public void checkMessageStatus(java.lang.String messageId)
                        throws IPWorksException

This method will retrieve the status of the specified message.

CheckMessageStatus will retrieve the last known status of the message stored on the server under MessageId . The bean will fire a MessageStatus containing the parsed response from the server.

IPWorksException

config

public java.lang.String config(java.lang.String configurationString)
                        throws IPWorksException

Sets or retrieves a beanconfiguration setting.

Config is a generic method available in every bean. It is used to set and retrieveconfiguration settingsfor the bean.

Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the bean, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY , you must call Config("PROPERTY=VALUE") , where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY") . The value will be returned as a string.

IPWorksException

connect

public void connect(java.lang.String userId,
                    java.lang.String password)
             throws IPWorksException

This method will bind as a transceiver to the SMPP service.

The Connect method will establish a socket connection to the SMPPServer and attempt to bind as a transceiver. Once the bind operation has completed, a Connected event will be fired containing the status of the connection.

IPWorksException

disconnect

public void disconnect()
                throws IPWorksException

This method will disconnect from the SMPP service.

Disconnect will send an unbind command and close the socket connection to the SMPPServer . After a unbind operation and socket closing, a Disconnected event will be fired containing the status of the unbind operation.

IPWorksException

doEvents

public void doEvents()
              throws IPWorksException

This method processes events from the internal message queue.

When DoEvents is called, the bean processes any available events. If no events are available, it waits for a preset period of time, and then returns.

IPWorksException

                           java.lang.String newMessage)
                    throws IPWorksException

This method replaces a previously sent message with a new one.

Assuming that there is a message on the SMPPServer stored under the value in MessageId , ReplaceMessage will replace that message with the value in NewMessage .

If there is no message corresponding to MessageId , the SMS service will respond with an error message.

IPWorksException

sendCommand

public byte[] sendCommand(int commandId,
                          byte[] payload)
                   throws IPWorksException

This will format and send a PDU using the specified command id and payload.

The SendCommand method offers a way to do more with the bean than is directly supported. This method takes a command id and a payload, which includes every required and optional field after the header, and will create the 16-byte header for it before sending it to the server. The response PDU is returned both in the PITrail and by this method.
