org.apache.commons.lang.SerializationException: java.lang.ClassNotFoundException

Working on the spring batch examples, and got the following error. To summarize, the classloader that the serializationtutils is using is not able to find this class.  I got around this error by creating my own copy of "SerializationUtils.java" in a new package and using this.  Since my SerializationUtils is in my webapp, there are no classloader issues.
