Java- SOAP Web service over Https
<p>I am very  new in SOAP with https .One of my projects requires making a SOAP call to access a web service over HTTPS.</p>

<p>the service provider only gave us three file .jks, .p12. and one code sample. .txt file
my first question is it possible to call Webservice without WSDL file.?</p>

<p>and I wrote the following client code with the help of sample code which service provider gave me .  </p>

<p>but I getting  this error message : java.net.SocketException: Socket is not connected: connect </p>
