java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session

Question

i am trying to integrate my already working spring project with hibernate, but this is the error i am getting on start up.

EVERE: Servlet.service() for servl         


        

Answer 1

This error is caused by transitive dependency of maven managed projects. Child will be using a particular version of an artefact but the parent would fetch a later version. In my case, I had to use

    
        org.hibernate
        hibernate-core
        4.3.11.Final
    

In the parent pom (i.e, I have specified the dependency version again in parent pom) to avoid this conflict.
