Cannot run a project

I get the following error when I am trying to run a project, copied from 'Pro Spring 3' (alpha version).
Here's the error I am getting :

Exception in thread "main" org.springframework.beans.factory.CannotLoadBeanCl assException: Cannot find class [com.apress.prospring3.ch2.StandardOutMesssageRende rer] for bean with name 'renderer' defined in class path resource [META-INF/spring/app-context.xml]; nested exception is java.lang.ClassNotFoundException: com.apress.prospring3.ch2.StandardOutMesssageRende rer

Any ideas guys?
Thank you.

The problem was the 3 's' in the class name inside app-context.xml
