title: Soap Exception error..Server was unable to process the request
body: <p>I am working on asp.net and Oracle and using a Web Service. Sometimes I get this error:</p>
  
  <blockquote>
    <p>System.web.services.protocols.soapexception: Server was unable to
    process request.. --> System.NullReferenceException: Object reference
    not set to an instance of an object.</p>
  </blockquote>
  
  <p>The main thing is I am not getting this error every time. But sometimes it comes and sometimes not. And also with the same data every time.</p>
  
  <p>I don't understand why it is like that. If I am not doing something right, then it should come all the time.</p>
  
  <p>Please help.</p>
