It's impossible to determine the cause with this limited info. Spring and Hibernate are giants each with its own configs and libraries, can be hundreds of reasons. Still by looking at the exception 2 things come to mind: 1. missing library 2. missing/wrong parameter in one of configs: web.xml, spring or hibernate properties/xml.
