For any given plug-in, you might need to customize the plug-in for your specific environment by adding to the defined components. For example, you might want to add an additional file to a given component.
Components are not extendable. To include additional components in your extended plug-in, you extend the component types for the plug-in, declaring additional components to use in the plug-in.
In the plugin-descriptor.xml file for your plug-in, modify the componentType child element of the component element to extend the component types that are referenced by your plug-in.
For more information about the componentType element, see Sun N1 Service Provisioning System 5.2 XML Schema Reference Guide.
