JRuby does not provide its own set of .rb libraries to run off; it expects that you will have C Ruby available somewhere. Obviously this allows us to run 90% of Ruby code and libraries exactly as C Ruby does, since we both use the same .rb files. I believe you have two options: 1. Try setting RUBY_HOME to the base directory of your C Ruby install (i.e. where you would find bin, lib, and so on). The JRuby startup script should be able to see that location and use the .rb files directly. 2. If that fails to work (let me know!), you can simply copy the C Ruby .rb files into the JRuby distribution directory: - copy %RUBY_HOME%\lib\ruby\1.8 directory as a whole into %JRUBY_HOME%\lib\ruby, so you have %JRUBY_HOME%\lib\ruby\1.8 containing all the same files. The second method is how most of the JRuby dev team runs JRuby, and it works very well. It also keeps JRuby separate from your Ruby install, so if you move or rename it JRuby will continue to work. It does, however, require to you update those libraries if you install a newer Ruby version. In the future, we hope to work out a way to distribute JRuby with the standard Ruby .rb files, so it provides a complete, working Ruby interpreter out-of-the-box...but that's a discussion for another day. JRuby also has a user mailing list on sf.net/jruby, the jruby-user list. Please join us and let us know if you have any more problems. Thank you for trying JRuby!
