I am trying to introduce RoR to my company and I have two ways of doing so in my mind: (1) rails/ibm_db2/passenger/DB2 - which is my preferable way but it is not really supported by company's infrastructure. (2) jruby/activerecord-jdbc/tomcat/DB2 - probably easier way to migrate relying on current infrastructure and java libs IF I have...
I'm looking to replace MRI with JRuby for some scripts. Would it be enough to provide an ant buildfile and the JRuby jar for them? Would something else be needed ( beside the JDK of course )? EDIT: when I'm saying "the JRuby jar", I'm meaning jruby-complete.jar. ...
I need to compile my jruby application into a standalone jar. How can I do this? ...
There is a post on http://kenai.com/ from Oracle's Ted Farrell which has an interesting statement: We are in the process of migrating java.net to the kenai technology. Does this mean java.net will be powered by Jruby on rails?? ...
Is anyone else out there running Rails 3 and JRuby-Rack, or Jetty and Rails 3? Any trick to it? I'm going insane with some debugging, and at this point I just want to know that it's possible. ...
My goal is to deploy a simple rails application on a windows server using the glassfish gem.

I'd rather not "reinvent the wheel" and I've found a Ruby project that provides functionality I need in my Java app (there is no preexisting Java project that does what I need - trust me, I've looked). So, best case scenario, I am able to run the Ruby code from my Java code (ala JSR223). However, this Ruby project depends on having seve...
So, I just moved to new project that is built on Ruby on Rails. I'm new to it and I'm still learning it. I can debug most of the application code, but it seems I can not debug unit test code and code that is tested. When I run unit testing in debug mode, I can set a breakpoint in unit test class code, for example where fixtures are adde...
I am testing Java classes with RSpec and JRuby. How can I stub out a call to super in an imported Java class in my RSpec test? For example: I have 2 Java classes: public class A{ public String foo() { return "bar"; } } public class B extends A public String foo() { // B code return super.foo(); } } I am just t...
I'm using JRuby 1.4.0 complete jar in one of my projects. I'm executing it from ant via the exec task: java -jar jruby1.4.0.jar script.rb script_params The thing is, on some computers I receive this: [exec] Exception in thread "main" :1: no !/ in spec (IOError) [exec] ...internal jruby stack elided...

I am working on porting a Rails app to JRuby and HSQLDB. My goal is to embed a database and the site within a single JAR file for deployment at customer sites. I have the site working quite well from the JAR, with a few notable problems. When I do the following with a pretty mundane ActiveRecord model: @total = SessionLog.count(:id) ...
Today I installed jruby by downloading it, extracting it to /home/james/jruby-1.4.0 and adding the following line to .bashrc export JRUBY_HOME=/home/james/jruby-1.4.0 export PATH=$JRUBY_HOME/bin:$PATH And then I installed some jruby gems via jruby -S gem install ... Jruby works fine, but this seemed to have cause two problems: 1) W...
Hi, I recently installed jruby on a machine that also has ruby installed on it. When I do rake something it now appears to be using the jruby interpreter. I'd like rake to use the ruby interpreter. I'd appreciate any help. ...
I'm attempting to build a Tropo Ruby application and I need to retrieve the result of an HTTPS GET. The Tropo platform doesn't have the httpclient Ruby gem so I can't use that. The Ruby engine used is JRuby so a suggestion has been to make use of the Java URL class to do the request. I've played around with it a little bit and I seem to ...
I have set my java min/max heap size to be the same as outlined in the Sun Docs for precise heap sizing using the following: -Xms768m -Xmx768m This works fine when I start tomcat, but if I run jruby from the command line it complains saying: Error occurred during initialization of VM Incompatible minimum and maximum heap sizes s...
Hi, I'm trying to use JRuby in a custom application, and I don't seem to be able to load the JRubyEngine object. My class looks like functionally similar to this: public class ScriptEngine { private static ScriptEngine engine = new JRubyEngine(); public void run(final String script, final Map<String,Object> input) { fi...
I'm working with JRuby and DataMapper running on Google AppEngine. I want to add a property to the AppEngine::User like :active_calendar which is a reference to a Calendar kind. I was able to do something in Python this way using a back reference. Are these possible in JRuby? Is this possible? Do I need to subclass the User? Can I even...
I'm trying out an experiment where I have an interface in java and implementing (including) it in an ActiveRecord or DataMapper model so that I can use AR or DM as a java ORM. However, both these libraries uses #allocate instead of #new to create instances. This prevents the instance returned from the Ruby script be casted to the interf...
