title: Remote Web service
body: <p>I am new to web services. I have a requirement in my project. They gave me a wsdl file and a web service link and document about the description of methods. </p>
  
  <p>In the documentation there is method called <code>retriveDocuments</code> with request parameters <em>request, loginUser, loginPassword, systemId, maxResults, searchCriteria</em>. </p>
  
  <p>They want me call webservice and get the required documents and show them in app. </p>
  
  <p>My question is how do I call web service and how do I pass all these parameters and get the result?</p>
