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.
