【问题描述】：
试图让 JMS 教程中的简单程序正常工作，我快要发疯了。本教程的源代码是here（忽略示例文件夹），但它没有正确组织（MDB 项目的依赖项必须包含在 SE 项目和其他小部分中）。如您所见，该程序由一个 EJB 模块组成，该模块包含一个要部署在应用服务器上的 MDB（我使用的是 Glassfish 5）和两个 Java SE 客户端，它们都有一个 main 方法。
在为 ConnectionFactory 和 Topic 创建和配置 JMS 资源后，MDB 模块被完美部署（如果资源的 JNDI 名称与 MDB 上指定的名称不同或根本不存在） ，部署失败）。但是，当我尝试使用相同的 JNDI 名称启动两个客户端中的任何一个时，会发生以下异常：

除了 GlassFish 5，我尝试同时使用最新版本的 Payara 服务器和 GlassFish 4，但问题仍然存在。请注意，我在客户端 SE 项目中包含了 Java EE 7 API 依赖项和 gf-client 5.1.0 依赖项，以及 MDB 项目的依赖项。正如堆栈似乎暗示的那样，ResourceAdapter 类丢失了，这很奇怪，因为我在项目中包含了 gf-client 依赖项。
这是 MDB 消费者的代码，部署得很好（不确定它是否有效，因为我无法在 SE 客户端启动生产者）：
@MessageDriven(mappedName = "jms/javaee7/Topic", activationConfig = {
@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
@ActivationConfigProperty(propertyName = "messageSelector", propertyValue = "orderAmount > 1000")
})
public class ExpensiveOrderMDB implements MessageListener {
@Override
public void onMessage(Message message) {
try {
OrderDTO order = message.getBody(OrderDTO.class);
System.out.println(String
.format("Expensive order received: %s", order));
} catch (JMSException e) {
e.printStackTrace();
}
}
}
这是 SE 生产者和消费者的代码：
public class OrderProducer {
private static final Float TOTAL_AMOUNT = 2500f;
public static void main(String[] args) throws NamingException {
Float totalAmount = OrderProducer.TOTAL_AMOUNT;
OrderDTO order =
new OrderDTO(1234l, new Date(), "Betty Moreau", totalAmount);
Context jndiContext = new InitialContext();
ConnectionFactory connectionFactory = (ConnectionFactory)
jndiContext.lookup("jms/javaee7/ConnectionFactory");
Destination topic = (Destination)
jndiContext.lookup("jms/javaee7/Topic");
try (JMSContext jmsContext = connectionFactory.createContext()) {
jmsContext.createProducer()
.setProperty("orderAmount", totalAmount)
.send(topic, order);
System.out.println(String.format("Sent order: %s", order));
}
}
}
public class OrderConsumer {
public static void main(String[] args) throws NamingException {
Context jndiContext = new InitialContext();
ConnectionFactory connectionFactory = (ConnectionFactory)
jndiContext.lookup("jms/javaee7/ConnectionFactory");
Destination topic = (Destination)
jndiContext.lookup("jms/javaee7/Topic");
try (JMSContext jmsContext = connectionFactory.createContext()) {
while (true) {
OrderDTO order = jmsContext.createConsumer(topic)
.receiveBody(OrderDTO.class);
System.out.println(String.format("Received order: %s", order));
}
}
}
}
我确信这个问题只是一些愚蠢且易于解决的问题，但我无法理解它。任何帮助将不胜感激。
