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 :-
