问题描述
尝试通过Liberty 20.0.0.1。上的jndi查找将xml消息发送到JMS队列时遇到问题。
我的server.xml是：
<?xml version="1.0" encoding="UTF-8"?>
<server description="Default server">
<featureManager>
<feature>el-3.0</feature>
<feature>localConnector-1.0</feature>
<feature>monitor-1.0</feature>
<feature>restConnector-2.0</feature>
<feature>jacc-1.5</feature>
<feature>servlet-4.0</feature>
<feature>jndi-1.0</feature>
<feature>concurrent-1.0</feature>
<feature>requestTiming-1.0</feature>
<feature>ssl-1.0</feature>
<feature>jdbc-4.0</feature>
<feature>cdi-2.0</feature>
<feature>jms-2.0</feature>
<feature>jaxrs-2.1</feature>
<feature>ejbLite-3.2</feature>
</featureManager>
<httpEndpoint id="defaultHttpEndpoint"
host="*"
httpPort="9080"
httpsPort="9443" />
<!-- Automatically expand WAR files and EAR files-->
<applicationManager autoExpand="true"/>
<applicationMonitor updateTrigger="mbean"/>
<messagingEngine>
<queue id="jmsQueue" forceReliability="ReliablePersistent" maxMessageDepth="5000"></queue>
</messagingEngine>
<jmsQueueConnectionFactory jndiName="jms/JMS_CF" connectionManagerRef="ConMgr">
<properties.wasJms
nonPersistentMapping="ExpressNonPersistent"
persistentMapping="ReliablePersistent"/>
</jmsQueueConnectionFactory>
<connectionManager id="ConMgr" maxPoolSize="10"/>
<jmsQueue id="jms_StockQueue" jndiName="jms/STOCK_JMS_QUEUE">
<properties.wasJms queueName="stockQueue"
deliveryMode="Application"
timetoLive="500000"
priority="1"
readAhead="AsConnection" />
</jmsQueue>
<jmsActivationSpec id="core_indexing/jms-mdb/StockMDB">
<properties.wasJms destinationRef="jms_StockQueue" />
</jmsActivationSpec>
</server>
和我的Java（非ejb类）代码是：
final InitialContext context = new InitialContext();
final QueueConnectionFactory qcf = (QueueConnectionFactory) context.lookup("jms/JMS_CF");
final Queue destination = (Queue) context.lookup("jms/STOCK_JMS_QUEUE");
queueConnection = qcf.createQueueConnection();
queueSession = queueConnection.createQueueSession(false,0);
final ObjectMessage message = queueSession.createObjectMessage(object);
queueSender = queueSession.createSender(destination);
queueSender.send(message);
但是，当我针对此容器内代码运行测试时，我得到了：
Intermediate context does not exist: jms/JMS_CF
javax.naming.NameNotFoundException: Intermediate context does not exist: jms/JMS_CF
at com.ibm.ws.jndi.internal.ContextNode.getTargetNode(ContextNode.java:125) ~[?:?]
at com.ibm.ws.jndi.internal.ContextNode.lookup(ContextNode.java:211) ~[?:?]

at org.apache.aries.jndi.DelegateContext.lookup(DelegateContext.java:161) ~[?:?]
at javax.naming.InitialContext.lookup(InitialContext.java:428) ~[?:1.8.0]
如果我更改Java代码，以便使用@Resource即完成连接工厂查找。
@Resource(lookup = "jms/JMS_CF")
private QueueConnectionFactory queueConnectionFactory;
错误是：
[ERROR ] SRVE0315E: An exception occurred: java.lang.Throwable:
javax.ejb.EJBException: CWNEN0030E: The server was unable to obtain an object
instance for the
java:comp/env/com.xyz.www.stock.api.ws.StockWS/queueConnectionFactory
reference. The exception message was: CWNEN1003E: The server was unable to
find the jms/JMS_CF binding with the javax.jms.QueueConnectionFactory type
for the java:comp/env/com.xyz.www.stock.api.ws.StockWS/queueConnectionFactory
reference.
用wasJmsServer-1.0和jJ-2.0替换jms-2.0 wasJmsClient-2.0摆脱了JNDI查找错误，但MDB无法激活。
解决方法
排序！
已替换
<feature>jms-2.0</feature>
使用
<feature>wasJmsServer-1.0</feature>
<feature>wasJmsClient-2.0</feature>
<feature>mdb-3.2</feature>
尽管 <jmsQueueConnectionFactory> 具有应用程序正在寻找的确切 JNDI 名称，但我也收到此错误。
原来的问题是连接工厂被配置为使用 IBM WebSphere MQ，而 Open Liberty 中没有。按照 Is there a "feature" in Open Liberty to connect to IBM MQ,equivalent to wmqJmsClient-2.0 in Liberty Profile? 中的步骤操作后，错误消失了。
