Migrating from Spring 2.0 and Hibernate 3.0 to Spring 3.1 and Hibernate 4.1

[Muhammad Abdul Arif]

Hi All,

We are trying to migrate our application which has Spring 2.0 and Hibernate 3 to Spring 3.1 and Hibernate 4.1. I have copied all the required jar files for both Spring 3.1 and Hibernate 4.1. But when i start the server iam getting below exception

Caused by: org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'com.ifs.csp.entity.productusers.manager.ProductUsersMgr$$EnhancerByCGLIB$$e1bcf54e' to required type 'com.ifs.csp.entity.productusers.manager.ProductUsersMgr' for property 'productUsersMgr'; nested exception is java.lang.ClassCastException: org.springframework.orm.hibernate4.SessionHolder cannot be cast to org.springframework.orm.hibernate3.SessionHolder

@Piyush Mangal

So that means hibernateTemplate cannot be used with hibernate4?

[Piyush Mangal]

Yes that is what is being suggested by Spring Team. You can also find blog on spring source around the same.

[Mark Spritzler]

Yes, since Hibernate 3.1 there is no gain or reason to use the HibernateTemplate. Hibernate removed the old boilerplate code that was needed, and is much cleaner. So no need to use the HibernateTemplate.
