Im trying to set up java and jruby on Windows, great work with the recent developments. In some of the recent examples of irb running on jruby it is ran like: C:\rails>jruby C:\ruby\bin\irb If I run this I get: c:\ruby\bin\irb:10:in 'require': No such file to load -- irb (LoadError) from c:\ruby\bin\irb:10" I have set both JAVA_HOME and JRUBY_HOME. Many thanks, Pete. PS. When setting JRUBY_HOME enviroment var it appears it cant have any spaces in the path, this is on Windows. And is most likly something to do this 'DOS'. -- Posted via http://www.ruby-forum.com/.
