ProxyFactory initialization error - Spring 1.2.1

[Todd Farmer]

Hi,

I'm having problems initializing a ProxyFactory object in my Spring 1.2.1-enabled test app. I was getting a ClassNotFound error, but resolved that by putting ASM in my classpath. Now, I get an IllegalAccessError:

The code is pretty straight-forward:

/*

 * 
 * Class HelloWorldWithDI.java
 * Package com.apress.example
 * 
 */
package com.apress.example;
 
import java.util.Properties;
 
import org.springframework.aop.framework.ProxyFactory;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.support.DefaultListableBeanFactory;
import org.springframework.beans.factory.support.PropertiesBeanDefinitionReader;
 
/**

 */
public class HelloWorldWithDI {
    
    public static void main(String[] args){
        BeanFactory factory = getBeanFactory();
 
       // pf.addAdvice(new AuditingInterceptor());
         
        MessageRenderer renderer = (MessageRenderer) factory.getBean("renderer");
        MessageProvider provider = (MessageProvider) factory.getBean("provider");
 
        ProxyFactory pf = new ProxyFactory(renderer);
                // pf.setTarget(new StandardOutMessageRenderer());
        /*
        MessageRenderer renderer2 = (MessageRenderer) pf.getProxy();
 
        renderer2.setMessageProvider(provider);
        renderer2.render();
 */
        renderer = (MessageRenderer) factory.getBean("renderer");
        provider = (MessageProvider) factory.getBean("provider");
        renderer.setMessageProvider(provider);
        renderer.render();
  
        
        
        
        
        
        
        
    }
    
    public static BeanFactory getBeanFactory(){
        DefaultListableBeanFactory factory = new DefaultListableBeanFactory();
        
       
        PropertiesBeanDefinitionReader rdr = new PropertiesBeanDefinitionReader(factory);
        Properties prop = new Properties();
        
        prop.setProperty("renderer.class", "com.apress.example.StandardOutMessageRenderer");
        prop.setProperty("provider.class", "com.apress.example.HelloWorldMessageProvider");
        
        rdr.registerBeanDefinitions(prop);
        
        return factory;
        
    }
 
}

I get the same exception regardless of whether I use the no-arg constructor or pass the target as the argument.

Any ideas why this is happening? ClassNotFound exceptions I can figure out; this I can't.

Thanks!

I figured it out. I was using CGLIB 2.0.2 when I needed 2.1. Bummer.
