stack trace problem in eclipse

I wrote a code as shown below to print stack trace. I am using eclipse IDE. I am unable to view the stack trace. I checked in开发者_开发问答 console and logcat.

catch (Exception ex)
    {
    //Exception handling
        ex.printStackTrace();
        Log.e("error in uploading", ex.getMessage());
    }

I logcat exception stack traces with...

catch (IOException e) 
        {
            Log.w(TAG, "IOException: " + Log.getStackTraceString(e));
        }

Is multiple devices showing in your DDMS=>Devices tab? If this is the case then select the device you are running your application. LogCat shows logging from one device at a time
