Service Component
A service component is a component that provides a (usually headless) service that can be used by other plugins. Typical services are, for example, an authorization service, license service or preferences service. They provide functionality that is available for all plugins, therefore they are implemented as a service.
The service component created by the archetype as described in the Quick start Start guide already provides a simple service component. The only thing you have to do is to implement the service and define the interface that it exposes. Other plugins will be able to define a dependency on this service component and use it.
When creating service components, be sure that they conform to the Plugin Development Guidelines (G083-G098, G112 and G151 in particular).
...
Form Component
A form component can be used to deploy form handlers into the XperienCentral application without a server restart. The form archetype generates a handler with an empty implementation. To implement the handler the doHandle method of the handler must be implemented.
When creating form components, be sure that they conform to the Plugin Development Guidelines (G083-G098 in particular).
