Using Java classes from Ruby in an OSGi environment

Question

I have to run some Ruby scripts using JRuby in an OSGi environment. In these Ruby scripts, I need to use Log4J, so I write something like:

require "C:\\path\log4j.jar"
# ....
ois = JRubyObjectInputStream.new(java.io.BufferedInputStream.new(socket.to_inputstream))            
log4j_obj = ois.readObject                      
event["message"] = log4j_obj.getRenderedMessage
# ....

It works fine, but now I want to install Log4J in the OSGi environment and use it in the Ruby script. How can I do that?

Answer 1

I honestly don't know much about OSGi, but I would hope that the container would put libraries like Log4J onto the classpath. If that's the case, then you can simply:

require 'log4j.jar'
