title: Getting Exception while generating the WebService when HashMap is passed as parameter
body: <p>I am trying to create a webservice which takes a VO and VO contains a parameter of type Map. I wrote this simple Service and trying to create the webservice out of it. While creating the webservice I am getting exception  that its not supported.</p>
  
  <pre><code> public MyVO myService(MyVO vo) {
      return vo;
  }
  
  public class VO{
    private String name;
    private Map&lt;String, Serializable&gt; paramsMap;  
  }
  </code></pre>
  
  <p>Error Which I am getting :</p>
  
  <p>The field or property  on the value type used via the service class has a data type, "java.util.Map", that is not supported by the JAX-RPC 1.1 specification. Instances of the type may not serialize or deserialize correctly. Loss of data or complete failure of the Web service may result.</p>
  
  <p>I am not sure what's wrong with this. Any help or work around?</p>
  
  <p>thanks in advance.</p>
