EJB3远程调用抛出ClassCastException

不知何故，当我尝试远程远程EJB3调用抛出ClassCastException时。EJB3远程调用抛出ClassCastException

服务器：

public interface CardManager extends Manager { 
    public CardCheckResponse check(CardCheckRequest request); 
} 


@Remote 
public interface RMICardManagerRemote extends CardManager { 
    static String CARD_CHECK_RMI_REMOTE_JNDI = "CardCheckRMI/remote"; 
} 


@Stateless 
@RemoteBinding(jndiBinding = RMICardManagerRemote.CARD_CHECK_RMI_REMOTE_JNDI) 
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED) 
public class RealRMICardManager implements RMICardManagerRemote { 
    private CardManager cardManager = injector.getInstance(CardManager.class); 

    @Override 
    public CardCheckResponse check(CardCheckRequest request) { 
    return cardManager.check(request); 
    } 

}

客户：

InitialContext remoteContext = new InitialContext(PropertiesUtil.getCardCheckProp()); 
RMICardManagerRemote rmiCardManagerRemote = (RMICardManagerRemote) remoteContext.lookup(RMICardManagerRemote.CARD_CHECK_RMI_REMOTE_JNDI); 

//throws ClassCastException 
CardCheckResponse cardCheckResponse = rmiCardManagerRemote.check(cardCheckRequest);

堆栈跟踪：

java.lang.ClassCastException: com.cardcheck.dto.CardCheckResponse cannot be cast to com.cardcheck.dto.CardCheckResponse 
    at $Proxy307.check(Unknown Source) 
    at com.xxx.cardCheck(RechargeAdapter.java:267)

我检查，如果它是重复的罐子，B ut并非如此。有没有人有任何想法来解决这个问题？

在此先感谢

解决！

这个问题是由JBoss的统一类加载器造成的。我解决了我在jboss-app.xml中创建自定义加载器的问题：

<loader-repository> com.cardcheck loader = cardCheck heard </ loader-repository>
