Re: java.util.List in rquest missed in WADL

[yhu]

Thanks Sergey, you answered the question I plan to to ask  I will check if it
work. 

My original question may be not clear, so I refine it and hope you can help.

I have a simple RESTful web service class:
@Path("/luckynumbers")
@Produces("text/plain")
public class LuckyNumbers {
    @GET
    @Path("/getWADL")
    @Produces("application/xml")
    @Consumes("application/xml")
    public String getWADL(@QueryParam("")RequestWrapper arg) {
        System.out.println(arg);
        return arg.toString();
    }

   @XmlRootElement
    public static class RequestWrapper {
        List<String> theList;
        String theRequest;

       @XmlElement(name="listItem")
        public Collection<String> getTheList() {
            return theList;
        }

        public void setTheList(List<String> theList) {
            this.theList = theList;
        }

        public String getTheRequest() {
            return theRequest;
        }

        public void setTheRequest(String theRequest) {
            this.theRequest = theRequest;
        }

       @Override
       public String toString() {
           return "RequestWrapper{" +
                   "theList=" + theList +
                   ", theRequest='" + theRequest + '\'' +
                   '}';
       }
   }
}

And the generated WADL (using _?wadl in IE) is:
  <application xmlns="http://wadl.dev.java.net/2009/02";
xmlns:xs="http://www.w3.org/2001/XMLSchema";>
  <grammars /> 
  <resources
base="http://localhost:8080/ws-rest-prototype/services/LuckyNumbersRest";>
  <resource path="/luckynumbers">
  <resource path="/getWADL">
  <method name="GET">
  <request>
   
  </request>
  <response>
  <representation mediaType="application/xml">
   
  </representation>
  </response>
  </method>
  </resource>
  </resource>
  </resources>
  </application>

The problem of the WADL is that "theList" in requestWrapper is not
generated. 

I find it is @QueryParam of the method argument causes this, if I remove it,
the WADL seems good. But without @QueryParam, the web service call fails.
What is your suggestion?
