Question

我正在使用wildfly 8.2.0开发MDB。使用的服务器配置为standalone-full-ha.xml。当行Connection connection = connectionFactory.createConnection()被执行时，我得到以下错误跟踪。

TRACE [org.hornetq.core.client] (pool-14-thread-1) getConnectionWithRetry::1 with retryInterval = 2000 multiplier = 1.0: java.lang.Exception: trace
at org.hornetq.core.client.impl.ClientSessionFactoryImpl.getConnectionWithRetry(ClientSessionFactoryImpl.java:1103)

at org.hornetq.jms.client.HornetQConnectionFactory.createConnection(HornetQConnectionFactory.java:107)

代码段

       try {
                InitialContext initialContext = new InitialContext();
                Object objRef = initialContext.lookup("java:/ConnectionFactory");
                ConnectionFactory connectionFactory = (QueueConnectionFactory) objRef;
                Connection connection = connectionFactory.createConnection();
            } finally {
                initialContext.close();
            }

在访问的消息上调用getObject()作为JMS时出现以下错误，并且由于上述错误而未初始化所需的队列。

JNDI名称java:/ConnectionFactory有问题吗？

代码段

ObjectMessage objMsg = (ObjectMessage) msg;     
Context c = (Context) objMsg.getObject();

错误

以下jms-connection-factory属性的值是否需要从java:jboss/DefaultJMSConnectionFactory修改为java:/ConnectionFactory或任何其他配置问题？

<subsystem xmlns="urn:jboss:domain:ee:2.0">
...
<default-bindings context-service="java:jboss/ee/concurrency/context/default" datasource="java:/TestDB" jms-connection-factory="java:jboss/DefaultJMSConnectionFactory" managed-executor-service="java:jboss/ee/concurrency/executor/default" managed-scheduled-executor-service="java:jboss/ee/concurrency/scheduler/default" managed-thread-factory="java:jboss/ee/concurrency/factory/default"/>
</subsystem>

请帮我解释错误发生的原因以及如何解决错误。非常感谢。

在standalone.xml中添加

print dsk

和Java代码

               <jms-connection-factories>
                    <connection-factory name="InVmConnectionFactory">
                        <connectors>
                            <connector-ref connector-name="in-vm"/>
                        </connectors>
                        <entries>
                            <entry name="java:/ConnectionFactory"/>
                        </entries>
                    </connection-factory>
                    <connection-factory name="RemoteConnectionFactory">
                        <connectors>
                            <connector-ref connector-name="netty"/>
