Package org.apache.catalina.util

Class Extension

java.lang.Object
org.apache.catalina.util.Extension
public final class Extension extends 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.
