Please suggest any solution so that I get able to access this web service.

Answer 1

Please refine your code, you are not forming your request message properly for this webservice. i think this line is causing problem.

return port.chkMob(directorynumber, email, alternate);

First of all, it's a soap webservice, your request message structure should look like this,

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inf="http://infotelconnect.com/">
   <soapenv:Header>
      <inf:AuthHeader>
         <!--Optional:-->
         <inf:Username>?</inf:Username>
         <!--Optional:-->
         <inf:Password>?</inf:Password>
         <!--Optional:-->
         <inf:IP>?</inf:IP>
      </inf:AuthHeader>
   </soapenv:Header>
   <soapenv:Body>
      <inf:chk_mob>
         <!--Optional:-->
         <inf:directorynumber>?</inf:directorynumber>
         <!--Optional:-->
         <inf:email>?</inf:email>
         <!--Optional:-->
         <inf:alternate>?</inf:alternate>
      </inf:chk_mob>
   </soapenv:Body>
</soapenv:Envelope>

Here you are forming header,

Map<String, Object> requestContext = ((BindingProvider)port).getRequestContext();

    requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, WS_URL);
    Map<String, List<String>> requestHeaders = new HashMap<String, List<String>>();
    requestHeaders.put("Username", Collections.singletonList("username"));
    requestHeaders.put("Password", Collections.singletonList("password"));
    requestHeaders.put("IP", Collections.singletonList("IP"));
    requestContext.put(MessageContext.HTTP_REQUEST_HEADERS, requestHeaders);

But while calling webservice operation chk_mob,

return port.chkMob(directorynumber, email, alternate);

you are simply providing only parameter1, parameter2, parameter3 as string which you are giving in this line from main method,

System.out.println(chkMob("parameter1","parameter2","parameter3"));

First make a proper soap envelope which i have mentioned above and then make webservice call by providng your soap envelope in that call. You can find plenty of examples and tutorials online for this java client. FYI, i have used soapui to generate that request message structure of yours.
