使用Glassfish 3.0.1 ...如果我有一个Web应用程序远程访问另一个应用程序中的EJB，并且重新部署了包含EJB的远程应用程序，我会得到一个javax.ejb.NoSuchEJBException（参见下面的stacktrace）。
不应该这样吗？我可以看到使用完全相同的JNDI名称成功部署了有问题的EJB。
除了重启Web应用程序之外，还有其他方法可以解决此问题吗？应该注意的是，在这个堆栈跟踪来自的特定示例中，我正在访问一个用CDI注入bean的servlet：
public class StatusServlet extends HttpServlet {
@Inject
private StatusService statusService;
@Override
public void doGet(final HttpServletRequest req, final HttpServletResponse res) throws IOException {
res.getWriter().write(statusService.getStatus());
}
}
使用以下生产者完成注入以获得正确的EJB：
public class StatusServiceProducer extends AbstractServiceProducer {
@EJB(name = "StatusService")
private StatusService service;
@Produces
public StatusService getService(final InjectionPoint ip) {
return service;
}
}
生成器用于使服务更容易包装在代理中，并且可以更容易地更改EJB的查找方式。
StatusService接口和实现如下：
@Stateless(name = "StatusService")
public class StatusServiceImpl implements StatusService {
private static final String OK = "OK";
public String getStatus() {
// Some code
return OK;
}
}
public interface StatusService {
String getStatus();
}
修改：提供了我自己的solution。还有更好的吗？
完整的堆栈跟踪：

答案 0 :(得分：2)
唯一的解决方案是不使用@EJB注入作为servlet中的一个字段（它在类加载时被注入，因此应用程序启动或首次使用servlet，而是为每个请求请求一个新实例。 遗憾的是，这确实意味着您无法使用@EJB注入注释，并且必须使用JNDI查找等以旧方式处理EJB。
答案 1 :(得分：1)
来自Glassfish论坛的discussion：
只有当EJB容器创建注入的新实例时，才会更新注入的引用。因此，如果您一直查找它，您将获得具有更新引用的实例，但如果您的代码保留在原始实例上，或者如果它被合并，则注入的引用仍然是陈旧的。
所以根本问题是对EJB的引用是陈旧的。我找到了两个解决这个问题的方法：
使用第二种解决方案，仍然可以使用CDI。您需要一个制作者和一个InvocationHandler。下面的代码是我在我的项目中使用的代码的简化版本，它可能无法正确编译，但它将显示用于实现此工作的想法和概念。 YMMV。
首先，在使用EJB的代码中，使用@Inject，如下所示：
public class Foo {
@Inject
MyEjb obj;
}
其次，您需要一个只返回EJB的包装版本的生产者：
public class MyEjbProducer {
@EJB(name = "MyEjb")
private MyEjb obj;
@Produces
public MyEjb getEjb(final InjectionPoint ip) {
InvocationHandler handler = new MyInvocationHandler(obj, MyEjb.class);
return (MyEjb)Proxy.newProxyInstance(obj.getClass().getClassLoader(), obj.getClass().getInterfaces(), handler);
}
}
第三，调用处理程序需要测试NoSuchEjbException并再次查找bean：
public class MyInvocationHandler implements InvocationHandler {
private MyEjb obj;
private Class lookupClass;
public MyInvocationHandler(MyEjb obj, Class lookupClass) {
this.obj = obj;
this.lookupClass = lookupClass;
}
public Object invoke (...) {
try {
return method.invoke(impl, args);
} catch (final InvocationTargetException e) {
if (e.getTargetException() instanceof NoSuchEJBException) {
// 1. look up EJB again
// 2. try calling invoke again
}
}
}
}
此代码绝不完整。一些代码，例如查找EJB并再次调用该方法，已被省略。
这样做会起作用。另一种方法是做类似的事情，但是向EJB添加一个单独的方法来检查陈旧性，而不是使用用户试图调用的方法。
你怎么看？有更好的解决方案吗？答案 2 :(得分：1)
此处已更正：
https://wikis.oracle.com/display/GlassFish/GlassFishv3.1EJB
保留独特的应用。重新部署的id / ejb id MS5 Mahesh EJB-6-1由MS3完成
因此，Glassfish 3.1应该可以正常使用。
