Oracle GlassFish Server 3.0.1 Application Development Guide

Using the Endorsed Standards Override Mechanism

Endorsed standards handle changes to classes and APIs that are bundled in the JDK but are subject to change by external bodies.

To use the endorsed standards override mechanism, copy the JAR files into the domain-dir/lib/endorsed directory, then restart the server.

For more information and the list of packages that can be overridden, see Endorsed Standards Override Mechanism.
