Using the following as a reference:
http://wiki.rubyonrails.org/rails/pages/HowtoGenerateJFreeCharts
I''m trying to build some charts and I need to call a .jar file from
within my controller. Here''s my code:
pipe = IO.popen("java -jar /raid/projects/Dashboard/charting/
requestByProject.jar "+params[:name]+"")
pipe.close
This gives me nothing, however, if I run the command via the command
line then it returns the images I need.
I''m running Rails through JRuby on a Sun Solaris machine if that helps
at all.
Thanks.

That''s why the article uses a command-line invocation of java. In JRuby, you should be able to do it natively via require ''java'' and include_class, instead of invoking java on the command line. This should get you started: http://kfahlgren.com/blog/2007/04/12/more-jruby-play-jfreechart/ - Mark. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
