我正在尝试在以下环境中创建一个企业应用程序（具有 Java EE、EJB 和 WAR 模块的环境）。我正在遵循这些说明（虽然这些说明与 Web 应用程序无关，但我找不到任何关于 Web 应用程序的文章）。
- NetBeans 7.2.1
- Glassfish Server 3.1.2（包含 Servlet 3.0 API）
- EJB 3.1
- JPA 2.0
- JSF 2.1
- 甲骨文 10g
我创建了一个类库（新项目 -> Java -> Java 类库）来放置javax.ejb.Remote将由无状态会话 bean 实现的远程（）接口。类库已添加到两个模块（EJB 和 WAR）的类路径中。
当尝试运行此应用程序时，会导致以下异常。

远程界面如下。
package admin.sessionbeans;
import entities.Transporter;
import java.util.List;
import javax.ejb.Remote;
@Remote(AdminSessionBeanRemote.class)
public interface AdminSessionBeanRemote
{
public List<Transporter> getAllTransporters();
}
无状态会话 bean。
package admin.sessionbeans;
import entities.Transporter;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless//(mappedName="adminSessionBean")
public class AdminSessionBean implements AdminSessionBeanRemote {
@PersistenceContext(unitName="wagafashion-ejbPU")
private EntityManager entityManager;
@Override
public List<Transporter> getAllTransporters()
{
return entityManager.createNamedQuery("Transporter.findAll").getResultList();
}
}
JSF 托管 bean。
package managedbeans;
import admin.sessionbeans.AdminSessionBeanRemote;
import entities.Transporter;
import java.util.List;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
@ManagedBean
@RequestScoped
public final class TransporterBean
{
@EJB
private AdminSessionBeanRemote adminSessionBeanRemote;
private List<Transporter>transporters;
public TransporterBean()
{
}
public List<Transporter> getTransporters()
{
transporters=adminSessionBeanRemote.getAllTransporters();
return transporters;
}
public void setTransporters(List<Transporter> transporters)
{
this.transporters = transporters;
}
}
我已根据此注释将所有实体类添加到类库中。
客户端 jar 应包含远程接口以及这些接口所依赖的任何类
大约一年前，当我使用 NetBeans 6.9.1 时，我开发了一些这样的应用程序。该版本的 IDE 不要求将远程接口放在单独的类库中。
我的 PC 上仍然安装了 NetBeans IDE 6.9.1，我尝试创建相同的应用程序（没有单独的类库，远程接口位于同一个 EJB 模块中）并且它按预期工作。
最后一件事：当我从两个模块（EJB 和 WAR）中删除这个类库并只部署 Java EE 模块（在 NetBeans 中用三角形表示的那个）时，它会执行其预期功能，从数据库中检索数据并显示在 JSF 页面上。
所以，我对这个异常的原因非常困惑，不能确定是因为类库问题还是我可能缺少的其他必需配置（尽管可能有一些 JNDI 查找我不知道的问题）。
如果有人有关于如何在 NetBeans 7.x 中创建企业 Web 应用程序的链接，那将非常有帮助。
