Spring is an open source component framework. Like Nucleus, Spring is based on JavaBeans.
The Oracle ATG Web Commerce platform lets you integrate existing Nucleus-based and Spring-based applications. For example, if you have a Spring-based web application that needs to access a property of an Oracle ATG Web Commerce user profile, you can use the integration to enable that.
The integration includes two classes:
atg.nucleus.spring.NucleusResolverUtil
enables Spring configurations to refer to Nucleus componentsatg.nucleus.spring.NucleusPublisher
enables Nucleus components to refer to Spring components
