How to authorize two way SSL Authorization in webservices for SOAP request?

Created the testscript using WSDL files. I am getting the error message while replaying the SOAP request:
HTTP/1.1 500 Server Error
Date: Tue, 04 Apr 2017 10:39:06 GMT
Content-Type: text/xml; charset=UTF-8
Content-Length: 645
Server: Jetty(...)

<?xml version="1.0"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"&gt;
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>Basic Authorization Token can not be found.</faultstring>.........................

In the Server authorization section have given the username and password. But still facing this issue. It has 2 way ssl authorization for webservices. How to implement authorization in this scenario?

Any suggestions or help is highly appreciated.
