Question

我在一个JAR文件上嵌入了JRuby，它正被我部署到WebSphere的EAR文件使用。当我从我的工作区调用该类时，它工作正常，但是当我在WebSphere中调用它时，这就是我得到的：

[3/31/11 11:21:15:984 BRT] 00000042 SystemErr     R classpath:/lib/xmlcompare.rb:4:in `require': no such file to load -- rubygems (LoadError)
    from classpath:/lib/xmlcompare.rb:4
    from classpath:/lib/xmlcompare.rb:1:in `require'
    from <script>:1

经过一些研究，我注意到当我从命令行运行JAR文件中的代码时，loadpath看起来像这样：

lib
lib/gems/builder-3.0.0/lib
lib/gems/rainbow-1.1.1/lib
lib/gems/syntax-1.0.0/lib
lib/gems/xml-simple-1.0.14/lib
file:/C:/RSA/workspace/sdops-XmlCompare/pkg/XmlCompare.jar!/META-INF/jruby.home/lib/ruby/site_ruby/1.8
file:/C:/RSA/workspace/sdops-XmlCompare/pkg/XmlCompare.jar!/META-INF/jruby.home/lib/ruby/site_ruby/shared
file:/C:/RSA/workspace/sdops-XmlCompare/pkg/XmlCompare.jar!/META-INF/jruby.home/lib/ruby/1.8
.

但是，在将JAR部署到WebSphere（与EAR捆绑在一起）之后，这里是loadpath的外观：

lib
lib/gems/builder-3.0.0/lib
lib/gems/rainbow-1.1.1/lib
lib/gems/syntax-1.0.0/lib
lib/gems/xml-simple-1.0.14/lib
C:/WINDOWS/TEMP//lib/ruby/site_ruby/1.8
C:/WINDOWS/TEMP//lib/ruby/site_ruby/shared
C:/WINDOWS/TEMP//lib/ruby/1.8
.

我已尝试在加载路径中添加更多条目：

成功：

lib
lib/gems/builder-3.0.0/lib
lib/gems/rainbow-1.1.1/lib
lib/gems/syntax-1.0.0/lib
lib/gems/xml-simple-1.0.14/lib
META-INF/lib/ruby/site_ruby/1.8
META-INF/lib/ruby/site_ruby/shared
META-INF/lib/ruby/1.8
C:/WINDOWS/TEMP//lib/ruby/site_ruby/1.8
C:/WINDOWS/TEMP//lib/ruby/site_ruby/shared
C:/WINDOWS/TEMP//lib/ruby/1.8
.

但这没有任何改变。

您是否知道在WebSphere内部运行时加载路径损坏的原因以及如何修复它？

尝试将以下内容添加到$ LOAD_PATH：

META-INF/jruby.home/lib/ruby/site_ruby/1.8
META-INF/jruby.home/lib/ruby/site_ruby/shared
META-INF/jruby.home/lib/ruby/1.8

JRuby加载路径搞砸了
