title: Getting message "The type org.aopalliance.aop.Advice cannot be resolved." in spring java program
body: <p>I'm trying to set up the spring AOP example from this page:</p>

  <p>I'm using Eclipse Indigo as my development environment. </p>
  
  <p>On these lines:</p>
  
  <pre><code>public class LogAfterThrowsAdvice implements ThrowsAdvice{
  
  public class LogAfterReturningAdvice implements AfterReturningAdvice{ 
  
  public class LogBeforeCallAdvice implements MethodBeforeAdvice {
  </code></pre>
  
  <p>I'm getting the message:</p>
  
  <blockquote>
    <p>The type org.aopalliance.aop.Advice cannot be resolved. It is
    indirectly referenced from required .class files</p>
  </blockquote>
  
  <p>I downloaded the org.aopalliance package from here:</p>
  
  <p><a href="http://sourceforge.net/projects/aopalliance/" rel="noreferrer">http://sourceforge.net/projects/aopalliance/</a></p>
  
  <p>The jar file is aopalliance-alpha1.jar. It does not contain the path org.aopalliance.aop. I'm wondering if I should be using a different aopalliance jar file?</p>
