[Resteasy-users] MessageBodyWriter for ArrayList<String> wrapped collection?

[Adam B. <ab...@lb...>]

I am wrestling with marshalling a simple ArrayList<String> collection.

In the case of XML, I am trying to obtain something like the following:
<status-values>
 <status>some status string</status>
 <status>some other status string</status>
</status-values>

Currently, I have the following interface:

@Path("/")
public interface RestService
{
   @GET
   @Path("status/list")
   @Produces("text/xml"), "application/xml", "application/json", "application/x-yaml"})
   @Wrapped(element = "status-values")
   List<String> getStatusValuesList();

   @GET
   @Path("status/response")
   @Produces({"text/xml", "application/xml", "application/json", "application/x-yaml"})
   @Wrapped(element = "status-values")
   Response getStatusValuesResponse();
}

and I have tried the following impls:

public class RestServiceImpl implements RestService
{
   @Override
   public List<String> getStatusValuesList()
   {
       return dataProvider.getStatusValues();
   }

   @Override
   public Response getStatusValuesResponse()
   {
       List<String> statuses = dataProvider.getStatusValues();
       return Response.ok(new GenericEntity<List<String>>(statuses){}).build();
   }
}

Each approach throws:
org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type: java.util.ArrayList of media type: application/xml

The exception is thrown because I am unsure how to specify the ArrayList values are Strings (not xml fragments) and should be wrapped in <status/> tags.

Given the quality of this API I think I am missing something obvious/simple. Any direction would be much appreciated. I'm using version 1.2.1.GA.
