I have downloaded struts-blank to play around. I was trying to use Spring
AOP with Struts 2. However, I am getting the following error:
2007-02-04 21:27:17,233 DEBUG AbstractBeanFactory - Bean with name

<bean id="helloWorldTarget" class="example.HelloWorld"/>
<!--<bean id="helloWorld" class="example.HelloWorld"

</beans>
Any help is greatly appreciated!
Thanks,
