Hello,

I just started to learn JRuby. So I installed "jruby_windowsjre_1_4_0.exe" on my windows xp professional machine.

I wanted to start with these examples:
http://java.sun.com/developer/technicalArticles/scripting/jruby/#gs

and I found the following error implementing the form example. I reduced the code such that the following two lines give the following error message:

The Code:

require 'java'
java.lang.boolean $_clickMeMode = true

The Error:

*****/jruby-1.4.0/lib/ruby/site_ruby/shared/builtin/javasupport/java.rb:5
0:in `method_missing': wrong number of arguments (1 for 0) (ArgumentError)
        from step1.rb:2

JRuby and Java version:

*****>jruby -v
jruby 1.4.0 (ruby 1.8.7 patchlevel 174) (2009-11-02 69fbfa3) (Java HotSpot(TM) C
lient VM 1.6.0_16) [x86-java]

So, why does this simple code not work?

Thanks for any help
