Hi, I'm trying to get result list of native query from a many-to-many pojo and getting the exception below. All my structure is based on net.sf.gilead sample. My pojo were made using netbeans with hibernate as orm and set as collection. Don't know why but the pojo that manage the many-to-many relation didn't define any collection of Set.... just
public class Empleadosgrupos implements Serializable {
...
@EmbeddedId
protected EmpleadosgruposPK empleadosgruposPK;
@JoinColumn(name = "idempleado", referencedColumnName = "idempleado", insertable = false, updatable = false)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Empleados empleados;
...
where Empleado and EmpleadosgruposPK are others pojos.
this fails on method onFailure(Throwable caught)
when i call EmpleadogrupoRemote.Util.getInstance().loadLastEmpleadosGrupo(new AsyncCallback() {
[WARN] StandardContext[]Exception while dispatching incoming RPC call

Hello,
First, please use the Gilead forum, since I do not follow the Hibernate4GWT forum anymore.
About your issue, it seems to come from your remote service signature, that should not return an array of object (forbidden by GWT serialization policy) but an array of persistent entity.
Regards
Bruno
