title: axis2: content length must be specified
body: <p>I am writing a SOAP service client using axis2. I generated the client code with wsdl2java, then I try to</p>
  
  <pre><code>Request req = new Request();
  req.setParameter("XXX");
  
  ServiceStub stub = new ServiceStub();                                     
  stub.remoteService(req);            
  </code></pre>
  
  <p>At runtime, I get an <code>AxisFault</code>: <code>Content length must be specified</code></p>
  
  <p>Any idea of what's going wrong or how to specify content length?</p>
