JRuby Java实现的Ruby解释器
JRuby，是一个采用纯Java实现的Ruby解释器，是面向Ruby、基于Java虚拟机(JVM)的一种解释程序，它结合了Ruby语言的简易性和功能强大的JVM的执行机制，包括与Java库 全面集成。Rails彻底加快及简化了Web应用的开发，不过它让人觉得不够成熟，特别是在高端企业级功能方面。另一方面，Java平台及其虚拟机、库和 应用服务器的速度、稳定性和功能方面却一直在提升，现在已被公认为是开发高端服务器。
JRuby 1.7.13 发布，这是 1.7 的第 13 次更新，1.7 版本主要目的是找出任意与 Ruby 1.9.3 不兼容的问题。
JRuby，一个采用纯Java实现的Ruby解释器，由JRuby团队开发。它是一个自由软件，在CPL/GPL/LGPL三种许可协议下发布。主要开发者有Charles Nutter、Thomas Enebo、Ola Bini、Nick Sieger等。
