The value of <property name="packagesToScan" value="com.limeroad.services.*.dao.*" /> should be the packages where your entities are in. So in your case it should be

<property name="packagesToScan" value="com.limeroad.services.hello.hibernate" />

Otherwise the entity scanning mechanism won't find your entity.
