Ehcache is an open source, standards-based cache used to boost performance, offload the database and simplify scalability. Ehcache is robust, proven and full-featured and this has made it the most widely-used Java-based cache.

There is a newer version: 2.10.9.2

/**
 * Provides support for servlet-based and filter-based Web applications.
 * 
 * Web application support is enabled by referencing the servlet
 * {@link com.sun.jersey.spi.container.servlet.ServletContainer} in the
 * web.xml.
 * 

 * For example, the following will deploy Jersey and automatically
 * register any root resource or provider classes present in the directory
 * "/WEB-INF/classes" or jar files present in the directory "/WEB-INF/lib":
 * 
 *   <web-app>
 *     <servlet>
 *       <servlet-name>Jersey Web Application</servlet-name>
 *       <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
 *     </servlet>
 *     <servlet-mapping>
 *       <servlet-name>Jersey Web Application</servlet-name>
 *       <url-pattern>/*</url-pattern>
 *     </servlet-mapping>
 *   </web-app>
 *


 * 
 * A deployment approach, that is more portable with respect to maven and 
 * application servers, is to declare the package names where root resource and provider
 * classes reside. For example, the following will deploy Jersey and
 * automatically register any root resource or provider classes present
 * in the package "managed", or any sub-packages.
 * 
 *   <web-app>
 *     <servlet>
 *       <servlet-name>Jersey Web Application</servlet-name>
 *       <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
 *       <init-param>
 *           <param-name>com.sun.jersey.config.property.packages</param-name>
 *           <param-value>managed</param-value>
 *       </init-param>
 *     </servlet>
 *     <servlet-mapping>
 *       <servlet-name>Jersey Web Application</servlet-name>
 *       <url-pattern>/*</url-pattern>
 *     </servlet-mapping>
 *   </web-app>
 * 
 * The deployment approach that is portable accross JAX-RS implementations is to
 * register an implementation of {@link javax.ws.rs.core.Application}. For
 * example given an implementation as follows:
 *  *   package com.foo;
 *
 *   import ...
 * 
 *   public class MyApplicaton extends Application {
 *       public Set<Class<?>> getClasses() {
 *           Set<Class<?>> s = new HashSet<Class<?>>();
 *           s.add(HelloWorldResource.class);
 *           return s;
 *       }
 *   }
 * 
 * then that implementation can be registered as follows:
 *  *   <web-app>
 *     <servlet>
 *       <servlet-name>Jersey Web Application</servlet-name>
 *       <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
 *       <init-param>
 *           <param-name>javax.ws.rs.Application</param-name>
 *           <param-value>com.foo.MyApplication</param-value>
 *       </init-param>
 *     </servlet>
 *     <servlet-mapping>
 *       <servlet-name>Jersey Web Application</servlet-name>
 *       <url-pattern>/*</url-pattern>
 *     </servlet-mapping>
 *   </web-app>
 * 
 * It is possible to combine package-based registration and 
 * {@link javax.ws.rs.core.Application}
 * registered by extending {@link com.sun.jersey.api.core.PackagesResourceConfig}
 * and registering the extended class, for example:
 *  *   public class MyApplication extends PackagesResourceConfig {
 *       public MyApplication() {
 *           super("org.foo.rest;org.bar.rest");
 *       }
 *   }
 * 
 * The above examples apply to Servlet-based configurations but they equally
 * applicable to Filter-based configurations. For example, the following
 * presents the same package-based configuration as above but utilizing a filter:
 *  *   <web-app>
 *     <filter>
 *       <filter-name>Jersey Web Application</filter-name>
 *       <filter-class>com.sun.jersey.spi.container.servlet.ServletContainer</filter-class>
 *       <init-param>
 *           <param-name>com.sun.jersey.config.property.packages</param-name>
 *           <param-value>managed</param-value>
 *       </init-param>
 *     </filter>
 *     <filter-mapping>
 *       <filter-name>Jersey Web Application</filter-name>
 *       <url-pattern>/*</url-pattern>
 *     </filter-mapping>
 *   </web-app>
 * 
 *
