Java Apache Camel JMS-异常不会随请求/回复返回给调用方

我使用ApacheCamel和JMS创建了一个简单的请求/应答设置。一切正常-调用被分派到服务器端服务，结果被返回到客户端。只有在服务器端出现异常时，才会将此异常返回给调用方。服务器上出现异常，客户端收到超时。我想在客户端接收异常

据我所知，可用的文档表明，我想要的应该是默认行为。我还玩弄了OneException条款，或者设置了另一条后传路线，但所有这些都没有帮助。所以我的问题是，我在设置中将异常返回给调用方时缺少了什么

以下是详细信息（代码简化）：

• 用于通信的JMS队列部署在独立JBoss中（7.1.1.FINAL）
• JNDI用于查找工厂以创建到队列的连接
• 客户端当前是一个运行在Jetty中的SpringWebApplication
• 该服务器目前是一个配置了Spring的简单独立Java应用程序
• Spring版本3.1.2.0发布
• ApacheCamel 2.10.2

客户端和服务器之间交换的DTO/异常：

public class RequestDTO implements Serializable {
    String payload;
    ...
}

public class ResponseDTO implements Serializable {
    String payload;
    ...
}

public class RmtServiceException extends Exception implements Serializable {
    public RmtServiceException() {
        super("Exception in service.");
    }
}

通过JMS调用的服务的接口：

public interface RmtService {
    ResponseDTO doSomething(RequestDTO request) throws RmtServiceException;
}

服务的实施：

@Component("rmtService")
public class RmtServiceImpl implements RmtService {
    public ResponseDTO doSomething(RequestDTO request) throws RmtServiceException {
        // Return a ResponseDTO if processing is successful,
        // otherwise throw an RmtServiceException
    }
}

客户端配置：

客户端收到一个超时：

所以再一次：其他一切都按预期工作，只有异常不会返回给调用方。非常感谢您在这方面的任何帮助！提前感谢。

请参阅transferException选项，您需要启用该选项来序列化异常并作为响应返回。该选项记录在JMS文档页面上：

Great，忽略了该选项。谢谢
