It is important to differentiate class names from Nucleus component names. Multiple components in Nucleus cannot have the same absolute name, but they can have the same class. For example, in the previous section the class Person is instantiated as the component /services/Person. It might also be instantiated as another component—for example, /services/Employee.

It is especially important to differentiate Java source files from the properties files required to build an application. For both types of files, the file’s position in the namespace also determines its position in the file directory. For example:

A component name and class name are sometimes the same—typically, when an application instantiates a single component from a given class. For example, the class atg.service.scheduler.Scheduler might be instantiated as the component /services/Scheduler.
