我在當前正在處理的一個小項目中遇到錯誤。我有一個在Wildfly應用服務器上運行的EJB項目。此服務器已連接到Oracle數據庫。這可以通過我在Eclipse中實現的測試客戶端正常工作。但是，我想通過Webservice使應用程序可用。所以，我實現了一個WebProject並通過其他客戶端我收到以下錯誤調用該WebProject：

的Wildfly應用程序服務器上的錯誤是：

我在WebProject Webservice的是：
package ws;
import java.util.Collection;
import javax.ejb.EJB;
import javax.jws.WebMethod;
import javax.jws.WebService;
import org.jboss.resteasy.logging.Logger;
import model.*;
@WebService
public class FacilityWebservice {
public static final int MILLI_SECONDS = 1000;
public static final String EJBName = "java:global/PIS/FacilityManager!session.FacilityManagerRemote";
private static final Logger log = Logger.getLogger(FacilityWebservice.class);
@EJB(mappedName = EJBName)
private FacilityManagerRemote facility;
@WebMethod
public Collection<Facility> getFacilities() {
log.info("<<<<<<<<<<<<<<<<<<<<<<<-------------getLocations");
log.info("webmethod getLocations called");
return facility.getAllFacilities();
}
}
的註冊名稱上Wildfly：
6:04:29,019 INFO [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-2) JNDI bindings for session bean named FacilityManager in deployment unit deployment "PIS.jar" are as follows:

java:module/FacilityManager!session.FacilityManagerRemote
java:jboss/exported/PIS/FacilityManager!session.FacilityManagerRemote
java:global/PIS/FacilityManager
java:app/PIS/FacilityManager
java:module/FacilityManager
這是我在WebApplication的接口
package model;
import java.util.Collection;
import javax.ejb.Remote;
import javax.ejb.Remove;
@Remote
public interface FacilityManagerRemote {
public Collection<Permission> getAllPermissions();
public Collection<Staff> getAllStaff();
public Collection<User> getAllUsers();
public Collection<Sequence> getAllSequences();
public Collection<Facility> getAllFacilities();
public Collection<MachineMasterData> getAllMachines();
public Collection<Productline> getAllProductlines();
public Collection<MachineDayData> getAllMachineDayData();
public Collection<GpsPoint> getAllGpsPoints();
public Collection<Facility> getFacilitiesByPrecedingFacility(Facility precedingFacility);
public Collection<Facility> getHighestTierFacilities();
public Facility getFacilityById(Facility facility);
@Remove
public void remove();
}
這是我在EJB項目接口：
package session;
import java.util.Collection;
import javax.ejb.Remote;
import javax.ejb.Remove;
import exceptions.NoSuchRow;
import model.*;
@Remote
public interface FacilityManagerRemote {
public Collection<Permission> getAllPermissions();
public Collection<Staff> getAllStaff();
public Collection<User> getAllUsers();
public Collection<Sequence> getAllSequences();
public Collection<Facility> getAllFacilities();
public Collection<MachineMasterData> getAllMachines();
public Collection<Productline> getAllProductlines();
public Collection<MachineDayData> getAllMachineDayData();
public Collection<GpsPoint> getAllGpsPoints();
public Collection<Facility> getFacilitiesByPrecedingFacility(Facility precedingFacility);
public Collection<Facility> getHighestTierFacilities();
public Facility getFacilityById(Facility facility);
@Remove
public void remove();
}
這是我的會話Bean在EJB項目：
package session;
import java.util.Collection;
import javax.ejb.EJB;
import javax.ejb.Remote;
import javax.ejb.Stateful;
import exceptions.NoSuchRow;
import model.*;
@Stateful
@Remote(FacilityManagerRemote.class)
public class FacilityManager implements java.io.Serializable {
private static final long serialVersionUID = 4460916846265144595L;
@EJB
private DefaultManager dm;
public FacilityManager() {
}
public Collection<Facility> getHighestTierFacilities(){
return (Collection<Facility>)dm.findByNamedQuery("Facility.findHighestTierFacilities");
}
public Collection<Facility> getFacilitiesByPrecedingFacility(Facility precedingFacility){
return (Collection<Facility>)dm.findByParameter
("Facility.findByPrecedingFacility", "precedingFacility", precedingFacility);
}
public Facility getFacilityById(Facility facility)throws NoSuchRow{
return (Facility)dm.findByPrimaryKey(Facility.class, facility.getFacilityID());
}
//TODO for testing
public Collection<Permission> getAllPermissions() {
return (Collection<Permission>) dm.list(Permission.class);
}
public Collection<Staff> getAllStaff() {
return (Collection<Staff>) dm.list(Staff.class);
}
public Collection<User> getAllUsers() {
return (Collection<User>) dm.list(User.class);
}
public Collection<Sequence> getAllSequences() {
return (Collection<Sequence>) dm.list(Sequence.class);
}
public Collection<MachineMasterData> getAllMachines() {
return (Collection<MachineMasterData>) dm.list(MachineMasterData.class);
}
public Collection<Facility> getAllFacilities() {
return (Collection<Facility>) dm.list(Facility.class);
}
public Collection<Productline> getAllProductlines() {
return (Collection<Productline>) dm.list(Productline.class);
}
public Collection<MachineDayData> getAllMachineDayData() {
return (Collection<MachineDayData>) dm.list(MachineDayData.class);
}
public Collection<GpsPoint> getAllGpsPoints() {
return (Collection<GpsPoint>) dm.list(GpsPoint.class);
}
}
我通過java的wsimport工具包爲WebApplicationClient生成了額外的類。我似乎無法弄清楚問題所在。我已經檢查過這個帖子： Can not set field to com.sun.proxy.$Proxy 但在我的情況下，FacilityManagerRemote是一個接口，而不是一個類。我不知道如何進一步解決這個問題。誰能幫忙？
