I have been looking for a GUI library for a while now. I had tried Monkeybars and Glimmer, both of which appealed the most to me, but I didn't manage to get them running (Glimmer is very old, won't load the gem properly) and Monkeybars seems quite dead, can't even run the Hello World examples in the video presentations. So I am wonderin...

Recently I've come across http://monkeybars.rubyforge.org/ and Rawr. It seems sufficient to build Java applications. My question is, is there any disadvantages of choosing this approach ? Jruby to Java ? Will my application suffer performance loss compared to writing it in Java ? For me the advantage is I don't have switch to Java, and ...

In the Java Debugger Interface documentation for the Location class, there's a paragraph discussing the "stratum" of the location. I've been looking around a bit for more detail on how one would go about implementing a new stratum (for, say, Scala or JRuby), but I haven't found much. Can anyone shed some light on the topic? ...
I've never used Jruby and I don't know why I should, but some people use it to complement the missing Java features in the Ruby language. So I wonder if Ruby will ever support the missing features Java does in the future so we do not need to learn Java? What do you think? ...
I'm trying to create a Stats counter (similar to the one in ostrich for scala by Twitter) but having a hard time making sure that all my threads have access to this. My Stats class is defined like this: class Stats @@counters = {} .. accessors .. def self.incr(counter, amt = 1) if !@@counters[counter] @@counters[coun...

The original code is: new PropertyDescriptor("splitEvaluator", CrossValidationResultProducer.class) which I've tried to port to: PropertyDescriptor.new("splitEvaluator", CrossValidationResultProducer) However, I get the error: no constructor with argume...
I am trying to run jruby -S rake db:migrate, but I do not want to start up a daemon in config/initializers whenever I do a migrate. Is there a way to do this? Up until now, I have just been moving the daemon file to a file with a .bak extension so that rails doesn't load it when I do the migrate. I suspect that this is a stupid way of ...
I was watching this video here, where Robert Nicholson discusses P8, an implementation of PHP on the JVM. At some point he mentions that they aim to surpass native PHP in performance some time in the future. He mentions JRuby and Jython, which started out slower than their native counterparts, but eventually surpassed them. Quercus, an...

I'm interested in promoting JRuby in our office as the platform hosting Rails applications. But how reliable is it? Is its performance better than MRI 1.8.7? JRuby 1.5 states that it is 100% compatible with Ruby 1.8.7, does this mean that JRuby can run any Ruby/Rails code? ...
For Web Applications I use Ruby on Rails. And now it's time to see if I can code Desktop Applications with Ruby. So I wonder which one I should choose. The way I see it is MacRuby+IronRuby vs JRuby. The former lets me have desktop applications for both Mac and Windows while the latter lets be have in both, but only learning one tool. ...
I'm having a difficult time locating an HTML parser that works with JRuby. I've become fond of using Nokogiri for HTML parsing, but Nokogiri requires the use of bxml2.dll, which I don't have available on my machine and am not sure that I can ensure that it is available on all users' machines. I attempted to use another favorite, Scruby...
