calling webservice from jsf managed bean which returns List throws exception
I created a web service in java which returns List which works perfectly fine. But, when i call that webservice in my JSF managed bean it throws exception. Here is the jsf Managed bean :-
package beans;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.xml.ws.WebServiceRef;
import services.Supplier;
import services.WsSupplierServiceService;
@ManagedBean(name = "SupplierBean")
@RequestScoped
public class SupplierBean {
@WebServiceRef(wsdlLocation = "WEB-INF/wsdl/localhost_8080/ShoppingMallBL-war/wsSupplierServiceService.wsdl")
private WsSupplierServiceService service;
@PostConstruct
public void init(){
services.WsSupplierService port = service.getWsSupplierServicePort();
System.out.println(port.getAll());
//supplierList = port.getAll();
}
public SupplierBean() {
}
private List<Supplier> supplierList;
public List<Supplier> getSupplierList() {
return supplierList;
}
public void setSupplierList(List<Supplier> supplierList) {
this.supplierList = supplierList;
}
}
Here is the exception, a very weird and long exception as usual from server :-

Caused by: Exception [TOPLINK-7242] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.ValidationException
Exception Description: An attempt was made to traverse a relationship using indirection that had a null Session. This often occurs when an entity with an uninstantiated LAZY relationship is serialized and that lazy relationship is traversed after serialization. To avoid this issue, instantiate the LAZY relationship prior to serialization.
