奇怪的spring结合jms问题，高手指点！！！

tzb08 2008-11-03 05:03:59

ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext-sender.xml");

		 JmsTemplate jmsTemplate=(JmsTemplate)ac.getBean("jmsTemplate");

我用这种方式得到jmsTemplate没问题。

换个方式：
将applicationContext-sender.xml放入web.xml中

<context-param>

		<param-name>contextConfigLocation</param-name>

		<param-value>

			/WEB-INF/classes/applicationContext-sender.xml

		</param-value>

	</context-param>

再在messageSender中用

private JmsTemplate jmsTemplate;



	public void setJmsTemplate(JmsTemplate jmsTemplate) {

		this.jmsTemplate = jmsTemplate;

	}

这种方式获得jmsTemplate时报了nullPoint。。。

望高手们点拨下！

applicationContext-sender.xml配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
