Basic Spring JMS Config question

[sona]

I have a simple bean which has a method to send messages to a queue defined in my spring-jms.xml. In the example code that I have seen and was able to get working, I was getting loading the config via a direct reference in code
------------------------------------------------------------------------
MyBean.java

Thread.currentThread().setContextClassLoader(
MessageHelper.class.getClassLoader());

context = new ClassPathXmlApplicationContext("spring-jms.xml");

Now I don't want to do this so I put the config in applicationContext.xml like this, but I am unable to get an instance of MyBean, i get the exception (see below)
----------------------------------------------------------------------------
<!-- My Bean -->
<bean id="myBean" class="com.xxx.MyBean">
<property name="context" ref="appContext"/>
</bean>

<!-- JMS Stuff -->
<bean id="appContext" class="org.springframework.context.support.ClassPa thXmlApplicationContext">
<constructor-arg>
<list>
<value>spring-jms.xml</value>
</list>
</constructor-arg>
</bean>

Ehrm WHY?!

Simply implement ApplicationContextAware, register your bean in the spring-jms.xml and you have access...

Or even better use Dependency Injection instead of accessing the Context yourself...
