Hi,

below is the output from my IRB session.

# ruby script/console
Loading development environment.
>> $DEBUG=true
=> true
>> require 'rjb'
Exception `MissingSourceFile' at
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27 - no
such file to load -- rjb
=> true
>> Rjb::load('lib/itext-2.0.6.jar')
=> nil
>>

I have done a gem install rjb, and have version 1.0.11 installed. Hope
this helps sole the problem. Thanks.

Kind regards,

Nick
