Hello:
I get the following exception in the HW application. I followed all the
specifications in the HW and my beans.xml file is as follows:
<beans>
<bean id="renderer" class="StandardOutMessageRenderer">
<property name="messageProvider">
<ref local="greetingProvider"/>
</property>
</bean>
<bean id="greetingProvider" class="HelloWorldMessageProvider"/>
</beans>
I have declared greetingProvider in HelloWorldMessageProvider with getter and
setter methods.
Exception
