远程EJB调用的事务

我有一个关于玻璃鱼交易和CORBA的奇怪问题。我可以解决问题，但我仍然不知道为什么会发生这种错误：

我有两个课程，我们称之为客户端和 RemoteImpl 。 客户端位于一台服务器上，远程位于另一台服务器上。

客户端看起来像这样（更简单的例子，而不是真正的代码）：

@Stateless
public class Client {

    @EJB(name = "TheRemoteEJB")
    protected Remote remoteEJB;

    @Schedule(hour = "*", minute = "*/5", persistent = false)
    @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
    public void doSomeStuff() {
      for(int i=0;i<300000;i++){
        remoteEJB.theMethodToCall(i);
        ... other code that may take a bit longer...
      }
    }
}

RemoteImpl 如下所示：

@Stateless
@Remote(RemoteInterface.class)
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public class RemoteImpl {

  @EJB
  private SomeJPAFacade facade;

  @Override
  public int theMethodToCall(int param) throws SomeException {
    Bean products = facade.findBySomeSelect(param);
    return bean.getAValue();
  }
}

其他使用的类是：

SomeException ：

public class SomeException extends Exception {
 public SomeException() {
   super();
 }
 public SomeException(String message) {
   super(message);
 }
}

和 RemoteInterface 

public interface RemoteInterface {
  public int theMethodToCall() throws SomeException
}

问题是，当 doSomeStuff 花费太长时间时，会引发CORBA异常：

我明确告诉ApllicationServer @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)，因为我不想跨越事务。但是这个例外似乎有一个交易。我一直以为交易不能跨越对另一个glassfish实例的远程调用？

我可以通过删除@TransactionAttribute并在客户端 - 类中添加@TransactionManagement(TransactionManagementType.BEAN)来解决问题。

但我仍然想知道为什么会发生这种错误。

感谢您的回复。

更新 Bugreport已在https://java.net/jira/browse/GLASSFISH-17535

1 个答案:

答案 0 :(得分：1)

NOT_SUPPORTED表示The container invokes an enterprise bean method whose transaction attribute NOT_SUPPORTED with an unspecified transaction context.

似乎未指定的上下文导致无效的事务异常。

通过使用bean托管事务，您告诉容器不要提供任何事务上下文，因此它可以防止该异常。

这对我来说感觉就像一个小虫子，我不太熟悉玻璃鱼，我的直觉告诉我这应该有效。
