I get the following error under NetBeans: C:/Program Files/NetBeans 6.5/ruby2/jruby-1.1.4/lib/ruby/site_ruby/1.8/builtin/core_ext/symbol.rb:1:in `const_missing': uninitialized constant Song (NameError) from C:\Projects\RubyLearning\RubyApplication1\lib\main.rb:4 when I try to run a two-file project built from the first example in Chapter 3: song.rb: # Sample code from Programing Ruby, page 23 class Song def initialize(name, artist, duration) @name = name @artist = artist @duration = duration end end main.rb: a_song = Song.new("Pie Jesu", "Sarah Brightman", "234") song.inspect Any suggestions or help much appreciated. Also suggestions for some newbie-tolerant discussion forum. Thanks in advance.
