This system administration feature is new in the Solaris Express 4/06 release.
The Common Agent Container (CAC) is a stand-alone Java program that implements a container for Java management applications. CAC provides a management infrastructure designed for the management functionality based on Java Management Extensions (JMXTM) and the Java Dynamic Management Kit (JDMK). The SUNCacaort package installs the CAC software in the /usr/lib/cacao directory. Typically, CAC is not visible to the user or administrator.
Two occasions when an administrator might need to interact with the container daemon are as follows:
When an application tries to use a network port that is reserved for the CAC
To regenerate the CAC certificate keys when a certificate store is compromised
