Overview

Java Caching System

Jakarta (part of Jakarta Turbine project)

Java Caching System (JCS) is a highly flexible and configurable solution to increase overall system performance by maintaining dynamic pools of frequently used objects. JCS goes beyond simply caching objects in memory. It provides several important features necessary for an enterprise-level caching system. JCS provides a framework with no point of failure, allowing for full session failover (in clustered environments), including session data across up to 256 servers. It also provides the flexibility to configure one or more data storage options like memory cache, disk cache, or caching the data on a remote machine.

OSCache

OpenSymphony

http://www.opensymphony.com/oscache/

OSCache caches sections of JSP pages and binary content such as PDFs or images. It provides both fast in-memory caching and persistent on-disk caching depending on the caching requirements. It also supports object caching in a cluster environment.

JOCache

ShiftOne

http://jocache.sourceforge.net

JOCache was developed to provide basic object caching. It supports clustered caching and can integrate with OR (object relational) models such as Hibernate.
