In this above code i am trying to do is if their are records in the database then i am sending sms to that destination number that i got from the datbase, if no records found then i am able to receive messages(towards GSM modem) in to the application.
if at all records are completed then i am able to receive messages,but if after receiving some messages if i updated some records in the table(for sending)the run method is not activated from 1st onwards means it is not able to send the sms's from the database.
So,what i have to do, as i know that the run method will work continuosly but why it is not working please reply to this as early as possible.
Thus it need any extra coding(I used some flag and tested like a producer and consumer problem but no effect on that).
regards,
sasi.
