jruby

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.

I'm pretty new to the whole JRuby world. I'm using RSpec on a pretty big test suite. I'd like to be able to run the specs frequently but the JVM takes so long to startup it's becoming a real time drain. Is there a way to keep the JVM running? or a way to get specs to run faster with JRuby? Nick Sieger There are two things you could look into: Run a nailgun server and send spec runs to it. jruby --ng-server & and then jruby --ng -S spec or jruby --ng -S rake Use spork. http://www.ruby-forum.com/topic/190163 I hear that Roger Pack has a version that may work with JRuby. http://github.com/rdp

I just recently started shifting attention towards deploying Ruby apps atop TorqueBox which of course is built atop Jruby. Hitherto I have been basically performing a bundle install and then tackling each gem along the way to jrubydom, but I've hit a couple gems that have taken me some considerable time to resolve due to needing to reimplement large portions of them. Is there a way to invoke bundler or rubygems to run through all gems and their deps to test if they require native c extensions and then return such a list? It sure would be nice to tackle some of the more minor items or even to

I am trying to use dBpedia with neo4j ontop of ruby on rails . Assuming I have installed neo4j and downloaded one of the dBpedia datasets . How do I import the dbpedia dataset into neo4j ? espeed The simplest way to load dbpedia into Neo4j is to use the dbpedia4neo library. This is a Java library, but you don't need to know any Java because all you need to do is run the executable. You could rewrite this in JRuby if you want, but regular Ruby won't work because it relies on Blueprints , a Java library with no Ruby equivalent. Here are the two key files, which provide the loading procedure.

Ruby has a universal idea of " truthiness " and " falsiness ". Ruby does have two specific classes for Boolean objects, TrueClass and FalseClass , with singleton instances denoted by the special variables true and false , respectively. However, truthiness and falsiness are not limited to instances of those two classes, the concept is universal and applies to every single object in Ruby. Every object is either truthy or falsy . The rules are very simple. In particular, only two objects are falsy : nil , the singleton instance of NilClass and false , the singleton instance of FalseClass Every
