Up until a commit yesterday, a "java_require" line was *required* in the file so it would know what .rb file to load to prepare your "MyRubyClass" on the Ruby side of things. But I committed a change yesterday so that if there's no java_require, it will actually produce a free-standing .class.
Can you give it a try with last night's build (or a current build from master)? http://ci.jruby.org/snapshots On Tue, Mar 16, 2010 at 10:29 AM, Ahmed Ragab Nabhan <anab...@uvm.edu> wrote: > Hi Developers, > > I have used the simple utility jrubyc that compiles a .rb file into .java. > When I try to run the resulting .class file, I got got an exception: > > $java -cp /.rvm/rubies/jruby-head/lib/jruby.jar:.
