I found this bit of information about the ACC (Application Client Container):
The ACC uses the IIOP ORB to contact the server during injection. The default port for the ORB is 3700. The Java Web Start support automatically sets the ORB-related properties to point to the correct ORB address. If you are running a cluster then this includes all currently-active cluster members' ORBs.

However, the documention, in general, seems light. While it is mentioned in the Development Guide:
Introducing the Application Client Container
The Application Client Container (ACC) includes a set of Java classes, libraries, and other files that are required for and distributed with Java client programs that execute in their own Java Virtual Machine (JVM). The ACC manages the execution of Java EE application client components (application clients), which are used to access a variety of Java EE services (such as JMS resources, EJB components, web services, security, and so on.) from a JVM outside the Oracle GlassFish Server. The ACC communicates with the GlassFish Server using RMI-IIOP protocol and manages the details of RMI-IIOP communication using the client ORB that is bundled with it. Compared to other Java EE containers, the ACC is lightweight. For information about debugging application clients, see Application Client Debugging.

The Application Client Container.
Although accessing an EJB from a client using JNDI is simpler than in EJB 2.x, it is still rather awkward. The good news is that we can dispense with JNDI altogether if the client runs from within an application client container (ACC). The EJB 3 specification does not mandate that an EJB-compliant application server provides an ACC but makes its inclusion optional. Consequently not all EJB-compliant application servers provide an ACC, however GlassFish does.

it's more of a general description. There's no official documentation on the ACC and its usage specifically?
