- public final class Extension
- extends java.lang.Object
Utility class that represents either an available "Optional Package"
(formerly known as "Standard Extension") as described in the manifest
of a JAR file, or the requirement for such an optional package. It is
used to support the requirements of the Servlet Specification, version
2.3, related to providing shared extensions to all webapps.
In addition, static utility methods are available to scan a manifest
and return an array of either available or required optional modules
documented in that manifest.
For more information about optional packages, see the document
Optional Package Versioning in the documentation bundle for your
Java2 Standard Edition package, in file
guide/extensions/versioning.html
