Each asadmin subcommand that you are adding must be represented as a Java class. To represent an asadmin subcommand as a Java class, write a Java class that implements the org.glassfish.api.admin.AdminCommand interface. Write one class for each subcommand that you are adding. Do not represent multiple asadmin subcommands in a single class.
Annotate the declaration of your implementations of the AdminCommand interface with the org.jvnet.hk2.annotations.Service annotation. The @Service annotation ensures that the following requirements for your implementations are met:
The implementations are eligible for resource injection and resource extraction.
The implementations are location independent, provided that the component that contains them is made known to the GlassFish Server runtime.
For information about how to make a component known to the GlassFish Server runtime, see Integrating an Add-On Component With GlassFish Server.
