如何从Ruby 1.8或1.9调用Java API

Now,I wonder whether I can and how can I wrap the same API in Ruby framework?

请告诉我这个问题是否无意义,或者是否可以某种方式改进.

这是想要的API的java doc参考.

这是我正在使用的JRuby代码：

require 'java'
module JXslt
  include_class "javax.xml.transform.TransformerFactory"
  include_class "javax.xml.transform.Transformer"
  include_class "javax.xml.transform.stream.StreamSource"
  include_class "javax.xml.transform.stream.StreamResult"
  include_class "java.lang.System"

  class XsltProcessor
    def transform(xslt,infile,outfile)
      transformer = @tf.newTransformer(StreamSource.new(xslt))
      transformer.transform(StreamSource.new(infile),StreamResult.new(outfile))
    end
  end # XsltProcessor
  class Saxon < XsltProcessor
    TRANSFORMER_FACTORY_IMPL = "net.sf.saxon.TransformerFactoryImpl"
    def initialize
      System.setProperty("javax.xml.transform.TransformerFactory",TRANSFORMER_FACTORY_IMPL)
      @tf = TransformerFactory.newInstance
    end
  end
end
