You can the examples:

http://code.google.com/p/jsmpp/source/browse/trunk/src/java/examples/org/jsmpp/examples/SimpleSubmitRegisteredExample.java

Check 

session.setMessageReceiverListener(new MessageReceiverListenerImpl());

So the point is you have to implement MessageReceiverListener and set it on session object.

Hi,

I am using JSMPP to send SMS and to get delivery receipt also. For SMS sending i have different connection using TX and to receive delivery receipt we have another connection RX. We are not using TRX as it is failing after every 2-3 SMSs. 

What is happening is that when we start the whole service SMS sending is working fine and for initial SMSs we are getting delivery receipt but it stops after few minutes. We have set enquire timer with value as 30 seconds.

Am I missing something? If at all is any connection issue I do not get any exceptions.

How to test if connection is valid for RX so that we can rebind.

Thanks and Regards,

Vikash Anand.

session.isOpen() may be useful.

Sometimes isOpen() may not be helpful (when the communication freezes over and isOpen still returns true) so you should record the last successful communication time, and rebind after a certain duration of inactivity.

Hi,

with jsmpp2.0 there is no method as isOpen(). Please suggest some other method. In order to test last activity we need to go to database but we are not sure about the duration we need to check for last SMS delivery receipt since SMS sending goes down drastically in night.

Thanks,

Vikash

My fault, sorry I did not recall the method name correctly then.

org.jsmpp.session.SMPPSession inherits the method getSessionState() from org.jsmpp.session.Session. That method returns an instance of the enum org.jsmpp.extra.SessionState -- you can use the methods isBound(), isReceivable() or isTransmittable() in SessionState to carry out your job.

Hi Shantanu,

Thanks for this great help. It finally solved the issue. I checked for isBound() and isReceivable() methods.

Thanks,

Vikash Anand.

Hi,

When we talked to the service provider they said that actually we are supposed to send them back deliversmresponse (something like this) with code "0x80000005". I have no idea how to do that and in which method. Is it on onAcceptDataSm method or in onAcceptAlertNotification. Please point me to any specs for the same or any help on this.

Thanks and Regards,

Vikash Anand.

Strange behaviour....

Is hard to know. You have to monitor the traffic using Wireshark. SMSC or ESME might close the connection, or one of them sending unbind command.

You can do something like session.getSessionState() to know the session state.
