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 can only bind as a transmitter, and thus can receive nothing outside of server command responses. However, 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 set the RecipientAddress and RecipientType properties 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 CheckMessage 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.

This property denotes the validity period of the current message.

The MessageExpiration property indicates the MC expiration time, after which the message should be discarded if not delivered to the destination. It can be set using absolute or relative time formats.

Absolute Time Format is a 16-character string represented as "YYMMDDhhmmsstnnp" where:

YY

the last two digits of the year (00-99)

MM

month (01-12)

DD

day (01-31)

IPWorksException

getMessageId

public java.lang.String getMessageId()

This is the id of the most recently sent message.

After a successful call to SendMessage , the MessageId property will be set to the server-assigned id of that message.

getMessagePriority

public int getMessagePriority()

This is the priority level of the current message.

When sending a message, the MessagePriority property will tell the server what type of priority to assign to the message. The effect of the message priority setting is dependent upon the Message Center manufacturer and the network on which the target recipient lies. For example, some MCs may immediately forward "urgent" messages, some networks may use the priority setting as a visual indicator of the message's urgency (e.g. blinking icons, etc.), and some networks may entirely ignore the priority setting.

IPWorksException

getPassword

public java.lang.String getPassword()

This is the user's password.

When binding to the SMPPServer , the client must provide a known user id and a valid password for that id.

There are two ways to bind: by calling Connect with a user id and password and will set the UserId and Password properties before connecting; or by setting those two properties and calling SendMessage while not connected.

setPassword

public void setPassword(java.lang.String password)

IPWorksException

getRecipient

public java.lang.String getRecipient()

This property corresponds to the first recipient in the recipient list.

For sending single messages, only the recipient is significant. Setting Recipient is equivalent to setting RecipientCount to 1, the first entry in RecipientAddress to the desired destination, and RecipientType to normal.

Note: Setting Recipient to "" (empty string) will reset the RecipientCount to 0.

setRecipient

public void setRecipient(java.lang.String recipient)
                  throws IPWorksException

This property corresponds to the first recipient in the recipient list.

For sending single messages, only the recipient is significant. Setting Recipient is equivalent to setting RecipientCount to 1, the first entry in RecipientAddress to the desired destination, and RecipientType to normal.

getRecipientAddress

public java.lang.String getRecipientAddress(int recipientIdx)
                                     throws IPWorksException

Array property that indicates the address of a particular recipient.

The RecipientAddress property can be used for setting single or multiple recipients. It is an array that is closely associated with the values in RecipientType and RecipientCount . Each entry corresponds directly to the same index in RecipientType .

For a recipient type of normal, the value in RecipientAddress should be either the dotted IPv4 of an SMS-enabled device or the directory number of a target mobile phone. For distributed lists, the value should be the name of the list as it is stored on the SMPPServer .

The first entry in this list can also be set using the Recipient property. Doing so will set RecipientCount to 1, and the first entry being the specified recipient with a type of normal.

IPWorksException

setRecipientAddress

public void setRecipientAddress(int recipientIdx,
                                java.lang.String recipientAddress)

IPWorksException

getRecipientCount

public int getRecipientCount()

This value indicates the number of recipients in the recipient list.

RecipientCount is the total number of message recipients specified by the client. It can contain any value from 0 to 255. When sending messages, this value is used to determine whether to send a single- or multi-recipient message.

It is important to keep this property in mind when sending messages. If the value is not changed between messages, the Smpp bean will send multi-recipient messages each time. Setting the value to a smaller number is the same as clearing all recipient values at indexes above that number.

There are two ways to manipulate the recipient list. The first is to manually set RecipientCount , RecipientAddress , and RecipientType . The second is to use AddRecipient , which will increment RecipientCount and set the last entry in the list.

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 behavior 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

IPWorksException

getUserId

public java.lang.String getUserId()

This value is used for identification with the SMPP service.

When binding to the SMPPServer , the client must provide a known user id and a valid password for that id.

There are two ways to bind: by calling Connect with a user id and password and will set the UserId and Password properties before connecting; or by setting those two properties and calling SendMessage while not connected.

setUserId

public void setUserId(java.lang.String userId)
               throws IPWorksException

This value is used for identification with the SMPP service.

When binding to the SMPPServer , the client must provide a known user id and a valid password for that id.

There are two ways to bind: by calling Connect with a user id and password and will set the UserId and Password properties before connecting; or by setting those two properties and calling SendMessage while not connected.

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

addRecipient

public void addRecipient(int recipientType,
                         java.lang.String recipientAddress)
                  throws IPWorksException

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

Rather than directly manipulating the array of recipients by setting all of the necessary properties, AddRecipient method can be used as a one-line way of incrementing RecipientCount , and setting the value of the last entry in RecipientType and RecipientAddress .

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

checkMessage

public java.lang.String checkMessage(java.lang.String messageId)
                              throws IPWorksException

This method will retrieve the status of the specified message.

CheckMessage will retrieve the last known status of the message stored on the server under MessageId . For delivered messages, the response will contain the date on which the message was delivered. For erred messages, the response will contain the error code related to the failure of delivery, and the bean will throw an exception.

IPWorksException

connect

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

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

The Connect method will establish a socket connection to the SMPPServer and attempt to bind as a transmitter. 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 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

replaceMessage

public void replaceMessage(java.lang.String messageId,
                           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.

IPWorksException

sendData

public java.lang.String sendData(byte[] data)
                          throws IPWorksException

This method sends data to the Recipient .

Up to 64KB of additional data can be supplied at a time for transmission to the SMPPServer . Unlike the SendMessage method, SendData can only send to one destination at a time. The target is whatever value is in the Recipient property, which corresponds directly to the first entry in RecipientAddress .

IPWorksException

sendMessage

public java.lang.String sendMessage(java.lang.String message)
                             throws IPWorksException

The methods sends a message to all recipients in the recipient list.

The SendMessage will send either a single- or multi-destination message depending on the value of RecipientCount . Each entry in RecipientAddress will receive the message. The return value of SendMessage is the server-assigned id of the message. The max size of the message sent is 256 bytes.

IPWorksException

addSmppEventListener
