Error creating bean with name 'sessionFactory'

[ajaygarkemukhu]

Hi Everyone,

I am trying to use Hibernate in my web app. But when I start the resin server I get an error stating:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in resource [/WEB-INF/simpleapp-servlet.xml] of ServletContext: Initialization of bean failed; nested exception is java.lang.NullPointerException: null

My simpleapp-servlet.xml looks like this:

What is the wrong with above XML file. I am using Resin 2.1.8, Hibernate 2.1.1 & MySQL 4.1.7.
