Hi Indu,
There is no property such as hibernate.connection.driver_class or other properties in org.springframework.jdbc.datasource.DriverManagerDataSource, which you have declared in datasource. So you are getting NotReadablePropertyException. It is having properties driverClassName,url,username and password. Try changing to this.

P:S: I would recommend you to move all the hibernate and other application related to beans to applicationContext.xml and use ContextLoaderListener to initialize it.

Thanks Prasad, it works like a charm. But why are you suggesting to use applicationContext.xml instead of spring-config ?

[Prasad Krishnegowda]

Just for the purpose of readability, because hibernate beans are application specific beans, the spring-dispatcher-servlet.xml, contains the handler mappings. If the application grows big, this would help in readability.
