Finally, the Body should look like this:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.holidaywebservice.com/HolidayService_v2/">
 <SOAP-ENV:Body>
   <ns1:GetHolidaysAvailable>

   </ns1:GetHolidaysAvailable>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
