     * Since this controller is set as the default controller in

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
    <OTA_HotelAvailRQ xmlns="http://www.opentravel.org/OTA/2003/05">
        <POS>
            <Source>
<RequestorID MessagePassword= "****" ID= "*****" Type="CHM"/>
</Source>
</POS>
<AvailRequestSegments>
<AvailRequestSegment>
<HotelSearchCriteria>
<Criterion>
<HotelRef HotelCode="00008164"/>
<StayDateRange Start="2016-04-01" End="2016-04-12">
</StayDateRange>
</Criterion>
</HotelSearchCriteria>
</AvailRequestSegment>
</AvailRequestSegments>
</OTA_HotelAvailRQ>



Kindly help me on this issue.

If you view the page source of your response, it says ...
&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; standalone=&quot;yes&quot;?&gt;&lt;OTA_ErrorRS ErrorCode=&quot;401&quot; ErrorMessage=&quot;Authentication fields are missing! Please try again with proper input.&quot; xmlns=&quot;http://www.opentravel.org/OTA/2003/05&quot;/&gt;

That suggests you have an authentication problem with your request.
