First of all: a NoClassDefFoundError is not to be confused with ClassNotFoundException.
Regarding to your actual problem: the error is pretty self-explaining. The mentioned class is missing in the runtime classpath. To fix this, just place the JAR file with the class in the classpath of the webapplication, which by default covers under each the /WEB-INF/lib folder.
