    Under the name mainDatasource , you have a bean declared, which is implemented by the org.springframework.jndi.JndiObjectFactoryBean class. And you are trying to inject it into a field with the DataSource type, and you get an error. JndiObjectFactoryBean does not have a DataSource class inheritance in its entire chain.
