Hello,

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:

       <result>/example/HelloWorld.jsp</result>

</struts>

Here is my applicationContext.xml:

<beans default-autowire="autodetect">

 <!-- =============================== Interceptors

 <bean id="timeLoggingAdvice" class="advice.TimeLoggingInterceptor"/>
 
 <!-- =============================== Advisor

     <value>execute</value>  
     </list>
    </property>
   <property name="advice">
     <ref bean="timeLoggingAdvice"/>
   </property>
 </bean>
 
 <!-- ============================== Spring Beans
================================= -->
 <bean id="helloWorld"
class="org.springframework.aop.framework.ProxyFactoryBean">
   <property name="proxyInterfaces">
     <value>example.IHelloWorld</value>
   </property>
   <property name="interceptorNames">
     <list>
       <value>timeLoggingAdvisor</value>
     </list>
   </property>
   <property name="target">
     <ref local="helloWorldTarget"/>
   </property>
 </bean>

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

 <!--<bean id="helloWorld" class="example.HelloWorld"
singleton="false"/>-->
   
</beans>

Any help is greatly appreciated!

Thanks,
Lee
