issue with REST service
I have simple REST service. It returns list of entity. (e.g. Event)
@GET
@Path("/events")
@Produces({ "application/json" })
public List<Event> findEvents() {
return eventBean.findEvents().getList();
}
It works fine if return type is List<Event>. If I change it to EntityDTO (which contains list of Event and int property as shown below), it gives below error.
EntityDTO.java
@XmlRootElement
@XmlSeeAlso({ Event.class })
public class EntityDTO<E> {
private List<E> list;
private int totalCount;
public List<E> getList() {
return list;
}
public void setList(List<E> list) {
this.list = list;
}
public int getTotalCount() {
return totalCount;
}
public void setTotalCount(int totalCount) {
this.totalCount = totalCount;
}
}
This is the error I get.

What am I missing? Any help would be appreciated.
Thanks.
RE: issue with REST service
Posted by "Patel, Sanjay" <Sa...@nemours.org>.
I was getting same error in both 1.5.1 and 1.6.0 snapshot.
I got it working by adding @XmlAnyElement(lax=true) in EntityDTO.java. I think it is required because of generic entity E.
@XmlAnyElement(lax=true)
public List<E> getList() {
return list;
}
Thanks,
