hi I am trying to use hpricot in JRuby. My problem is the following. If I have this code: #!ruby require 'hpricot' require 'open-uri' # load the RedHanded home page doc = Hpricot(open("http://redhanded.hobix.com/index.html")) where do I put it? Into my controller? Because its not accepting it there. And if I'm supposed to put it...
Is there a way I can explicitly cast one Java object to another Java class from JRuby? Sometimes I want to be able to invoke SomeJavaClass#aMethod(MySuperClass) rather than SomeJavaClass#aMethod(MyClass) from JRuby. From Java, I'd do this: someJavaObject.aMethod( (MySuperClass) myObj ); but I didn't see a #cast ruby method or an...
I just installed jruby-1.4.0 to play around with it. I'm noticing however that warbler is packaging this by default with my rails deploy. My production uses jruby-complete-1.3.1 (which I've added to my lib dir to freeze the version) but warbler is adding jruby-core-1.4 when it packages everything up. That's a bit worrisome for me as I...
I found startling difference in CPU and memory consumption usage. It seems garbage collection is not happening when i run the following nokogiri script require 'rubygems' require 'nokogiri' require 'open-uri' def getHeader() doz = Nokogiri::HTML(open('http://losangeles.craigslist.org/wst/reb/1484772751.html')) puts doz.xpath("html[1]...
is there a problem with doing? will there be some constraint on resources? #main.rb (1..100000).each do |loop| `ruby dosomething.rb` end The reason i am doing this is because main.rb needs to be run in Jruby. Somescript.rb runs faster using less resource in just Ruby, hence i am running it as shell command. ...
i need a way to run following nokogiri script #parser.rb require 'nokogiri' def parseit() //... end and call the parseit() while running below main.rb in jruby #main.rb require 'parser' parseit() Of course the problem is jruby cannot find 'nokogiri' as I have not installed it aka nokogiri-java via jruby -S gem install nokogiri T...
Hi, Does (J)Ruby support such things like Calendar in Java or CultureInfo in .NET? I want to be able to write code in Ruby similar to this: locale = Locale.new("en-GB") date1 = "30/12/2000".to_date(locale) locale = Locale.new("en-US") date2 = "12/30/2000".to_date(locale) Locale.current = "ru-RU" date2 = "30.12.2000".to_date # uses t...
I suspect that the corporate firewall is preventing gems from getting installed. I have HTTP_PROXY defined and I'm able to view remote gems via the following command: jruby -S gem list -r But when I go to install a gem, I get a 404: jruby -S gem install rails Is there a good workaround for resolving this issue other than maintainin...
I have been programming for a while with Ruby and I really enjoy it. Lately I started having the need of compiling some ruby code. For several reasons using Ruby2exe is not an option for me. So I decided to give Jruby a try (generating a jar would be good enough). I am using windows and I installed java JDK 6u17 (at C:\Program Files\Jav...
I'm packaging up a rails app with warbler and I want app specific logging. I've added the log4j and commons-loggin jar to the WEB-INF/lib directory, and I want to add log4j.properties to the WEB-INF/classes directory. The problem is, I also want environment specific logging, so my staging/production use different properties (ie. INFO i...

My application is developed on Rails 2.3.5, its running fine on Webrick, Mongrel, Tomcat and Glassfish.

As developing an Java application bundled with 'jruby-complete.jar', it is desired not to put required rubygems localally, but instead packaged it along with the application. Obviously we don't want to touch 'jruby-complete.jar'. What's the better way of packaging these rubygems? ...

I can't seem to find what the current syntax for using java classes in Jruby is. This link text article lists: include Java include 'java' require 'java' As valid options, though it says the last option is pre 1.0 and doesn't work. The Jruby Wiki however says to use require 'java' And for including classes I've seen MyClass = Java::...
I have developed a Ruby on Rails application and successfully deployed on Weblogic using Jruby and Warbler (which creates a war file based on the settings in config/warble.rb). I believe although Jruby comes with inbuilt Ruby 1.8 and 1.9, by default it uses 1.8 and I want to test the same rails application in Ruby 1.9 within JRuby as I...
