Hi, For those who might not be aware, rjb is a killer gem for using java classes inside your rails app (or any ruby code). Check it out at: http://rubyforge.org/projects/rjb/ I was able to successfully use it in one of my apps that required some code that is only available in java. And it''s much nicer than having to compile a java app, then shell out using backticks, get back the return

Heya all -- I recently downloaded the RJB 1.1.1 gem, and the install seemed to go fine. However, when I try to require ''rjb'' I get the following error: no such file to load -- rjb Has anyone seen this before? Any thoughts what it could be?

Greetings. I am trying to list all keys in a java.util.HashMap field. The Java code to do this looks like: # Collection c = hMap.values(); # # //obtain an Iterator for Collection # Iterator itr = c.iterator(); # # //iterate through HashMap values iterator # while(itr.hasNext()) System.out.println(itr.next()); So, I took a stab at the ruby version: # I have a java hashmap called fields

I''m trying to interact with a java library (Aspose Slides) inside of my Rails 3 app. I''m trying to get the rjb gem installed but I keep running into the same error when I try to start the app: [BUG] cross-thread violation on rb_gc() (null) Abort trap I''m on OSX 10.6.6, running ruby 1.8.7-p174 (via RVM) and Rails 3.0.4.

I am trying to do file i/o with rails and rjb and can''t figure out a way to make this work.

My latest stupid web trick, built, with love, in Rails: http://wordie.org Make lists of words. See who else likes the same words. Basically, it''s a dating site.

Railsters: ActiveRecord''s validation system puts other database systems to shame. However, the newbies might not know how to write a regexp that excludes a match, instead of tests for it. Understand - I''m just asking this question to help them. I have been using Regexps since ''grep'' on Xenix! But the newbies here might not know how to do this:

I''d like to try autocompletion, and my understanding based on AWDWR:2, and on various website tutorials, is that I should install the script.aculos.us javascript library. My question is how to do that. The instructions on their site tell me to "Put prototype.js, scriptaculous.js, builder.js, effects.js, dragdrop.js, slider.js and controls.js in a directory of your website,

I have been waiting for a tipping point to start using Ruby applications instead of PHP applications. My criteria include the availability of Ruby and RoR web hosts and Ruby equivalent applications readily available for PHP. I keep finding PHP applications to fill my needs but not Ruby applications or hosts offering Ruby support. For example, I use content management systems which are

I''ve been working through the book ''Beginning Ruby on Rails E-Commerce'' which is very heavy on Test Driven Development. As in, you have to write tests for scaffolding methods and validations and crap like that. And then they fail. And you KNOW its the test not the method. So you spend 2x the time writing a test that has to be adapted when requirements change. You

I have skimmed through many web pages, how to''s and editorials, my final conclusion is that the programming language for this particular part of the program is going to be Ruby. There are many reasons: 1. Apple will support it in 10.5 2. There seems to be a lot of support for it in the Mac community 3. Ruby developers seem to be Mac people. 4. There is better documentation than

Railsoids: FormTestHelper rules. It tests your response.body form at the same time as it triggers your action, with all the parameters in that form. This obviously improves quality. But it took issue with this: submit_form ''validate_stuff'' do |form| form[''IBhidden''] = ''validate'' end The field IBhidden is a hidden field. To be

Railsers: As usual for a product written very rapidly, most of its documentation assumes some other documentation told you something critical. For example, the file form_helper.rb tempts me with this documentation: # <% form_for :person, @person, :url => { :action => "update" }, :builder => LabellingFormBuilder do |f| %> That''s beautiful. Now what do I
