Android httpclient calling restfull web service

according to following url I have created a requesthelper for calling a restfull webservice(.Net). http://as400samplecode.blogspot.com/2011/09/android-asynctask-httpclient-with.html

every time I call it from Android device it give error. in one of the topic at stackoverflow I suggest add '/' character at the end of the URL. You can find my url formats and given errors as listed below.
