JACC (Java Authorization Contract for Containers) is part of the J2EE 1.4 specification and defined by JSR-115. JACC defines an interface for pluggable authorization providers. This provides third parties with a mechanism to develop and plug in modules that are responsible for answering authorization decisions during J2EE application execution. The interfaces and rules used for developing JACC providers are defined in the JACC 1.0 specification.
The Application Server provides a simple file-based JACC-compliant authorization engine as a default JACC provider. To configure an alternate provider using the Administration Console, open the Security component under the relevant configuration, and select the JACC Providers component. For details, see the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Administration Guide.
