提问by Long Thai
I know that this question has been asked many times, but I still have an exception even after following all the answers. My configs are:
我知道这个问题已经被问过很多次了，但即使在遵循所有答案之后我仍然有一个例外。我的配置是：
context.xml
上下文.xml
<Context>
<Resource
name="jms/ProdConnectionFactory"
description="Prod JMS Connection Factory"
auth="Container"
userName=""
password=""
type="org.apache.activemq.ActiveMQConnectionFactory"
factory="org.apache.activemq.jndi.JNDIReferenceFactory"
brokerURL="tcp://jmshost:61616"
brokerName="ProdActiveMQBroker"
/>
</Context>
web.xml
网页.xml
<web-app>
<resource-ref>
<description>Prod Connection Factory</description>
<res-ref-name>jms/ProdConnectionFactory</res-ref-name>
<res-type>org.apache.activemq.ActiveMQConnectionFactory</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
Java code:
爪哇代码：
Context context = new InitialContext();
ActiveMQConnectionFactory factory = (ActiveMQConnectionFactory) context.lookup("java:comp/env/jms/ProdConnectionFactory");
And the exception that I receive is:
我收到的例外是：

Can anyone take a look and let me know where I'm wrong. Thanks

The reason is described here: appname.xml is different than context.xml, i.e. it contains less resources defined in context.xml. appname.xml should be updated everytime a application is redeployed, but there's an issues in redeployment which leaves appname.xml unchanged. The issue is fixed after I update appname.xml
原因在这里描述：appname.xml 与context.xml 不同，即它包含的context.xml 中定义的资源较少。每次重新部署应用程序时都应更新 appname.xml，但在重新部署时存在一个问题，使 appname.xml 保持不变。更新 appname.xml 后问题已解决
