    No-arg default constructor error when deploying Web Service

    Max Korn Newbie

      Hi all !

      I'm badly stuck with a weird exception that I get when I deploy a Webservice on JBoss As 7.1.1.

       

      The Web Service itself is simple and returns in a method a List of Counters:

       

      @XmlRootElement
      public class Counter implements Serializable {

       

       
      private Counter() {
        
      }

      private Counter(int price) {
                 this.price = price;
        
      }

      private int id;
      private String desc
      private int price;
      . . . .  
      }


      @WebService
      public class CounterWS implements CounterWSItf, Serializable {
      @Inject InfoService service;
       

      @Override
      public  List<Counter>  getCounters() {
             
         return service.getCounters();
      }

       

      However I get the following exception once I deploy it:

       

      Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
      com.telco.model.Counter does not have a no-arg default constructor.
              this problem is related to the following location:

      As you can see, there is a default constructor in the Counter class. I've tried also removing the other constructor without success.

      By removing the type <Counter> from the List it actually deploys but once I invoke it from the Client, I get another type of Error, that the Counter type is unknown (!!).

       

      Is it a bug or something else I'm missing ?

      Thanks a lot
