I have a spring hibernate code. To my knowledge the code is correct. I am not able to identify where it is going wrong. In the DAO class I declared SessionFactory variable. It says
Caused by: java.lang.IllegalArgumentException: No SessionFactory specified
at org.springframework.util.Assert.notNull(Assert.jav a:112)
at org.springframework.orm.hibernate3.SessionFactoryU tils.doGetSession(SessionFactoryUtils.java:283)
This can be caused by a dirty classpath with different versions of Spring libraries all over the place.
Cleanup it and align it to the one and same Spring version with the correct versioned dependencies.
