HI,
I am using Logica SMPP APIs to connect to a SMSC for sending and receiving SMS.
I am using JDK 1.6 and Apache Tomcat 6.
The web application is being deployed in Windows Server 2003.

After running the application for couple of days, when I try to send a message, I am getting this error :

java.io.IOException: Not connected
      at com.logica.smpp.TCPIPConnection.send(TCPIPConnection.java:344)
      at com.logica.smpp.Transmitter.send(Transmitter.java:69)
      at com.logica.smpp.Session.send(Session.java:931)
      at com.logica.smpp.Session.send(Session.java:984)
      at com.logica.smpp.Session.submit(Session.java:585)
      at com.san.sms.smpp.SMPPMessaging.submitRequest(SMPPMessaging.java:777)
      at com.san.sms.smpp.SMPPMessaging.submitTextMessage(SMPPMessaging.java:403)
      at com.san.sms.smpp.SMPPMessaging.handleMessage(SMPPMessaging.java:314)
      at com.san.sms.smpp.SMPPMessaging.access$2(SMPPMessaging.java:310)
      at com.san.sms.smpp.SMPPMessaging$MessageQueListener.run(SMPPMessaging.java:258)

I think it is getting unbound. But I am neither sending any unbind requests nor the SMSC.
What might be the problem.
Is it an OS related issue or network related issue.

Thanks.

From the error it seems that your application is not bounded to SMSC. But as you said the application was running & neither you nor SMSC sent any unbound request then first thing i'll look for is the time of Inactivity over the connection!!

Do you get this error while you try to send SMS after certain period of time? Try to find that do you get this error after inactivity of 1 hr or may be 24 hrs over connection. If yes, check with you SMSC that do they have a timeout mechanism in place. This can also happen because of some firewall rule over you network.

Solution to this can also be scheduler that sends can send dummy SMS as Keep Alive message (if you messaging is free ;) )

cheers

Thanks for the reply.

It might not be because, I am sending Enquirelink request every 5 minutes & getting proper response.
What might be the problem then??
