JSR107 (JCache)

About

JCache is the API being defined in JSR107. It defines a standard Java Caching API for use by developers and a standard SPI ("Service Provider Interface") for use by implementers.

Releases

  • 13 March 2012: 0.5 Early Draft Submission uses this release.
  • December 2011: 0.4
  • 12 October 2011: 0.3
  • 16 August 2011: Initial release, 0.2

Maven snippet:

<dependency>
  <groupId>javax.cache</groupId>
  <artifactId>cache-api</artifactId>
  <version>0.5</version>
</dependency>

Snapshot Releases

Snapshot releases of jars for binaries, source and javadoc are available.

Download the cache-api from https://oss.sonatype.org/index.html#nexus-search;quick~javax-cache

or use the following Maven snippet:

<repository>
    <id>sonatype-nexus-snapshots</id>
    <name>Sonatype Nexus Snapshots</name>
    <url>https://oss.sonatype.org/content/repositories/snapshots</url>
    <releases>
        <enabled>false</enabled>
    </releases>
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
</repository>

<dependency>
  <groupId>javax.cache</groupId>
  <artifactId>cache-api</artifactId>
  <version>0.2</version>
</dependency>

Javadoc

The JavaDoc is available as a jar with the releases. We also have the latest JavaDoc online.

Specification

The evolving specification is available online on as a Google Doc.

Reference Implementation

The reference implementation ("RI") source is available on GitHub.

This implementation is not meant for production use. For that we would refer you to one of the many open source and commercial implementations of JCache.

The RI is there to ensure that the specification and API works.

For example, some things that we leave out:

  • implementation of transactions.
  • tiered storage. A simple on-heap store is used.
  • replicated or distributed caching

Why did we do this? Because a much greater engineering effort, which gets put into the open source and commercial caches which implement this API, is required to accomplish these things.

Having said that, the RI is Apache 2 and is a correct implementation of the spec. It can be used to create new cache implementations.

Building From Source

Building uses Maven in all modules. Maven 2.2.1 and 3.0.4 have been tested.

See each module's README.md for build instructions.

Testing Implementions of JSR107

The jsr107tck module contains a domain, tests and an implementation-tester. The implementation-tester allows an implementation, packaged as a Maven module, to be specified on the command line and tested. For example a fictional Acme company implementation could be tested as follows:

mvn -Dtest=CacheManagerFactoryTest \
    -Dimplementation-groupId=acme.cache \
    -Dimplementation-artifactId=acme-cache \
    -Dimplementation-version=0.1-SNAPSHOT \
    test

Mailing list
