I am making a web application on STS. I am using jars of Spring 3.1.0 and HIbernate 4.0.1. I am including jars in project build path.
In DAO layer when I am trying to make a HibernateTemplate object , it is not getting instantiate, It is null there. I don't understand why it is null.

Earlier I was getting an error like NoClassDefinitionFound: org.springframework.orm.hibernate3.HibernateTemplate....Then I included these jars in WEB-INF->lib folder and then this error was removed but still hibernateTemplate object is null. Can there be any issue regarding position of beans.xml in project folders. ? Can anyone help me.

Below is code for my beans.xml and Userinfo.java.

Regardless.

YOU SHOULD NOT BE USING HibernateTemplate.

It was only valuable/benefitial if you are using Hibernate 3.0 and before.

Any version of Hibernate 3.1 or higher, you should be injecting the SessionFactory into your Repositories and calling getCurrentSession()

So much that HibernateTemplate in Spring 3.1 is very deprecated.
