java.io.IOException While invoking webService from Service

I am invoking web service from my application. I have used Service instead of ASyncTask to invoke the web service. I am getting java.io.IOException. I have tested with AsyncTask also but its working fine. Problem is only when i use Service(background thread). Please help me to resolve this issue.

Logcat is

        Object root = envelope.getResponse();
    } catch (Exception e) {
        e.printStackTrace();
    }

}

Thanks in advance

Basically Services is an application component that can perform long-running operations in the background and does not provide a user interface. And AsyncTask allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.

Working with web-services, you have to call it Asynchronously, because asynchronous invocation enables Web service clients to initiate a request to a Web service, continue processing without blocking, and receive the response at some point in the future.

So,

As per your app requirement, You have to call web-service using Services. But what you have done is, You are calling your web-service direct in Services, instead of that, just call your web-service into asynctask and call async task from service. Thats all.

Get back with your feedback.

Happy coding...

Please provide your code. You just start the background service and in onStart method of service call the method to invoke web service and stop the service after the back ground process get completed.
