Configuration Using Java class

[MikeT]

I'm trying a simple example of configuration by class injection:

My main is

package com.apress.prospring3.ch5.javaconfig;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationC onfigApplicationContext;


public class JavaConfigSimpleExample2 {

public static void main(String[] args) {

ApplicationContext ctx = new AnnotationConfigApplicationContext(AppConfig.class );

MessageRenderer renderer = ctx.getBean("messageRenderer", MessageRenderer.class);

renderer.render();

}

}


My AppConfig class is:

package com.apress.prospring3.ch5.javaconfig;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configurati on;

// Inform Spring this is a java-based configuration file
@Configuration
public class AppConfig {

@Bean
public MessageRenderer messageRenderer() {
MessageRenderer renderer = new StandardOutMessageRenderer();

// Setter injection of MessageProvider
renderer.setMessageProvider(messageProvider());

return renderer;
}

@Bean
public MessageProvider messageProvider() {
return new ConfigurableMessageProvider();
}

}

When I run the main I get the error:

Exception in thread "main" java.lang.IllegalStateException: Cannot load configuration class: com.apress.prospring3.ch5.javaconfig.AppConfig

Can anyone help? Thanks

p.s. I do have cglib.jar in my build path

I discovered the problem, I had to load the asm-3.3.1.jar also, working fine now.
