无法将Rails应用程序部署到WebLogic [英] Failed to deploy Rails app to WebLogic

问题描述

我正在尝试将非常简单的Rails应用程序部署到Oracle WebLogic Server.它只是由诸如" jruby -S rails new myapp "之类的命令创建的默认应用程序.
如果运行开发服务器(" jruby -S rails server ")，效果很好. 但是，当我将其部署到WebLogic时，会收到一个异常:

I'm trying to deploy very simple Rails application to Oracle WebLogic server. It's just a default application created by a command like "jruby -S rails new myapp".
It works fine if I run a development server ("jruby -S rails server"). But when I deploy it to WebLogic, I receive an exception:

org.jruby.rack.RackInitializationException: no method 'getInstance' for arguments (org.joda.time.tz.CachedDateTimeZone) on Java::OrgJodaTimeChrono::GJChronology

我的环境:
操作系统:Windows 8.1
Java:Java(TM)SE运行时环境(内部版本1.7.0_40-b43)
jRuby:jruby 1.7.10(1.9.3p392)2014-01-09 c4ecd6b
WebLogic:12.1.2
滑轨:4.0.2
莺:1.4.0

My environment:
OS: Windows 8.1
Java: Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
jRuby: jruby 1.7.10 (1.9.3p392) 2014-01-09 c4ecd6b
WebLogic: 12.1.2
Rails: 4.0.2
Warbler: 1.4.0

推荐答案

这是WebLogic的一个常见问题，是由冲突的JodaTime(jar)库引起的.

this is a common issue with WebLogic caused by conflicting JodaTime (jar) library.

可通过添加weblogic.xml描述符并将WL告知Wiki中 WEB-INF/lib 详细信息中的"prefer" (Java)类来修复: https://github.com/jruby/jruby-rack/wiki/Deploying-with -WebLogic

it's fixable by adding a weblogic.xml descriptor and telling WL to "prefer" (Java) classes from WEB-INF/lib details at the wiki : https://github.com/jruby/jruby-rack/wiki/Deploying-with-WebLogic
