I'm using SMSlib for sending messages using serial gsm modem.I need to send SMSs multiple times using the same application. I ran the SMSlib example without issues and it worked fine.But when I tried to use the same code under a webservice it can only used for one time. And when trying to use for second time it gave the following error. I used a python client.
C:\Users\k4n\Desktop\web>python SendSMS.py
No handlers could be found for logger "suds.client"
Traceback (most recent call last):

And this is the SMSlib out put when trying to send SMS for second time.

Why I'm getting this error? how can I solve this?
Got the Answer
Remove the gateway after stopping the service
String message1 = url;
OutboundMessage msg = new OutboundMessage("mygroup", message1);
Service.getInstance().sendMessage(msg);
System.out.println(msg);
Service.getInstance().stopService();
Service.getInstance().removeGateway(gateway);//remove the gateway
This is worked for me.
