我在java中创建了一个Web服务，返回List，工作得很好。但是，当我在我的JSF托管bean中调用该webservice时，它会抛出异常。这是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;
}
}
这是一个例外，一个非常奇怪且长期的异常，就像服务器一样： -

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.
