Integrating JSF, SPRING and Hibernate and always getting the error-org.springframework.beans.factory.CannotLoadBeanClassException - spring

Question

I'm new to Spring. Trying to build a Web project using JSF Spring and hibernate in Maven but seems my application is not able to get the spring configuration XML.
Below is the Stack Trace:
WARNING: Exception encountered during context initialization - cancelling refresh attempt

Answer 1

I believe your problem has to do with the component scan. In this blog, it seems that in order to use your configuration, you must add the following annotation, #ManagedBean to your beans.
Still, there is an easier way to do a complete scan, which is allowing Spring to do it for you. For this you might try deleting the following lines from your applicationContext.xml.
<!-- service -->
<bean id="userDetailsService" class="co.MyJavaCode.spring.service.impl.UserDetailsServiceImpl" />
<!-- dao -->
<bean id="userDetailsDao" class="co.MyJavaCode.spring.dao.impl.UserDetailsDaoImpl" />
After deleting those lines, add the following line to the same file.
<context:component-scan base-package="co.MyJavaCode"/>
This will automatically scan all your files that have either the #Component or #Service annotation. I Added co.MyJavaCode as the base package, because it looks like every class is inside that package, but if not, just create a base package and add everything to it and use it as reference for your auto-scan. Hope it helps!
