Class not found using javaConfig [duplicate]

Question

I am using annotations to dynamically create a Bean, I get the following errors.

package demoproject;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class ProductFactory {

    public ProductFactory() {
        // TODO Auto-generated constructor stub
    }

    @Bean   
    public Product josh(){
        Product josh = new Battery();
        josh.setId("cdrw");
        josh.setPrice(100);
        return josh;
    }
}

web.xml

 <!-- Bean for JavaConfig -->
   <bean  class='demoproject.ProductFactory' />
   <!-- be sure to include the JavaConfig bean post-processor -->
   <bean class="org.springframework.config.java.process.ConfigurationPostProcessor"/>

Error log

How can I know what's causing the error, and is there any fix I can try for this?

Answer 1

from spring 3.0 on, you don't need org.springframework.config.java.process.ConfigurationPostProcessor any more, simply define the Java-config class as a bean within the XML-config.

<bean class="demoproject.ProductFactory" />

try remove

<bean class="org.springframework.config.java.process.ConfigurationPostProcessor"/>
