title: "Missing SEI" when generating artifacts with WSGEN
body: <p>I am a beginner in the development of web services. I want to generate artifacts using wsgen.exe. </p>
  
  <p>Here is my code:</p>
  
  <pre><code>  package com.calc.ws;
  
    import javax.jws.WebService;
  
    @WebService
    public class Calculator {
        public int add(int a, int b) {
            return (a + b);
        }
        public int sub(int a, int b) {
            return (a - b);
        }
    }
  </code></pre>
  
  <p>The problem I'm facing is when I want to generate the artifacts from the command line with this command (one liner):</p>
  
  <pre><code>C:\Program Files\Java\jdk1.7.0_05\bin\wsgen 
       -cp "c:\users\mico\workspaceSOA\calcWS\src\com.calc.ws.Calculator" 
       -verbose 
       -d "C:\users\mico\classes\"
  </code></pre>
  
  <p>I get this error: </p>
  
  <pre><code>Missing SEI.
  </code></pre>
  
  <p>What is causing this?</p>
