我的任务是将 Tomcat 7 连接到远程 IBM MQ。我尝试在 server.xml 文件中创建 JNDI 资源，但它不起作用。我用了例子 from .
另外，我在这个例子中添加了 username 和 password。但是当我从 Java 代码调用 JNDI 资源时出现错误。
<Resource
name="jms/MyQCF"
auth="Container"
type="com.ibm.mq.jms.MQQueueConnectionFactory"
factory="com.ibm.mq.jms.MQQueueConnectionFactoryFactory"
description="JMS Queue Connection Factory for sending messages"
HOST="<mymqserver>"
PORT="1414"
CHAN="<mychannel>"
TRAN="1"
QMGR="<myqueuemanager>"/>
<Resource
name="jms/MyQ"
auth="Container"
type="com.ibm.mq.jms.MQQueue"
factory="com.ibm.mq.jms.MQQueueFactory"
description="JMS Queue for receiving messages from Dialog"
QU="<myqueue>"/>
我已将所有必需的 *.jars 从 [IBM sphere]/lib/java 下载到 Tomcat lib 文件夹。请帮助我，mb 我做错了。也许我需要一些 IBM 客户端，但我不知道它是什么。

IBM MQ 库的版本是:
Implementation-Version: 7.0.1.8 - k701-108-120201
我在 server.xml 中的当前资源是:
<Resource
name="jms/MyQCF"
auth="Container"
type="org.springframework.jms.connection.CachingConnectionFactory"
factory="com.ibm.mq.jms.MQQueueConnectionFactoryFactory"
description="JMS Queue Connection Factory for sending messages"
HOST="192.168.204.73"
PORT="1415"
username="***"
password="***"
CHAN="JAVA.CHANNEL"
TRAN="1"
QMGR="U.SEND"/>
<Resource
name="jms/MyQ"
auth="Container"
type="com.ibm.mq.jms.MQQueue"
factory="com.ibm.mq.jms.MQQueueFactory"
description="JMS Queue for receiving messages from Dialog"
QU="U.RECEIVE"/>
我的java代码:
System.out.println("servlet page*****************");
Context ctx = null;
try {
ctx = (Context) new InitialContext().lookup("java:comp/env");
System.out.println("ctx: " + ctx);
} catch (NamingException e) {
e.printStackTrace();
}
QueueConnectionFactory qcf = null;
try {
qcf = (QueueConnectionFactory) ctx.lookup("jms/MyQCF");
System.out.println("qcf: " + qcf);
} catch (NamingException e) {
e.printStackTrace();
}

最佳答案
我刚刚决定为此使用 Spring Boot - https://github.com/lzp4ever/IBM_WebSphere_MQ_Spring_Boot_JMS .
但是我遇到了新问题。我在这个链接上的新问题:multiple jms connection factory
关于java - Tomcat 7 + JNDI 资源 + IBM WebSphere MQ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47616048/
