title: Issue with setting the content type for http request header with axis2
body: <p>I have a  webservice  client code which accesses a service (Axis2  based). I tried changing the content type in the request header using the following code.</p>
  
  <pre><code>ServiceClient serviceClient = stub._getServiceClient();
  Options options = serviceClient.getOptions();
  options.setProperty(HTTPConstants.CHUNKED, "true");
  options.setProperty(Constants.Configuration.ENABLE_HTTP_CONTENT_NEGOTIATION,"true");
  options.setProperty(Constants.Configuration.MESSAGE_TYPE,"text/xml");
  </code></pre>
  
  <p>But the above code was not working for the content type <code>text/xml</code> .But It worked when I used the content type <code>application/xml</code> .I was not able to set the content type as <code>text/xml</code>.</p>
  
  <p>Can anybody give me a solution for this?</p>
