JRuby OpenSSL Error

Question

I am having problems configuring JRuby to work properly with OpenSSL. Googling has revealed that this is a pretty common occurence, but none of the solutions I've read have worked for me. Here is my setup:

• Ubuntu 9.10
• jruby 1.5.1
• jruby-openssl (0.7)

Here is the error:

irb(main):001:0> require 'jruby/openssl/gem_only'
=> true
irb(main):002:0> require 'openssl'
=> true
irb(main):003:0> OpenSSL::Digest::OPENSSL_VERSION_NUMBER
NameError: uninitialized constant OpenSSL::Digest::OPENSSL_VERSION_NUMBER

Interestingly, require 'openssl' returns true even if I don't have the jruby-openssl gem installed. According to this link, that shouldn't happen?

Trying to load the gem explictly with require 'rubygems' and gem 'jruby-openssl' doesn't help.

Answer 1

In the few instances that I've used JRuby, I'd head to the community's IRC channel when I ran into problems. The project devs hang out in the room for most of the working day and are very helpful when questions are asked. Check this page out for details.

Are you sure you are looking at the right constant?
