I am getting the exception:

Error creating bean with name 'sessionFactory' defined in ServletContext resource

Is it happening because of jar mismatch? If you need any further details please let me know.

log

ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
