I need to get the jruby version for logging & debugging purposes. I tried looking around JRuby.runtime for a 'version' method, but I didn't find anything useful. I also thought about using %x{jruby -v}. It works in most cases, except that there is always the possibility that more than one jruby version are installed, and I want to get ...
I get the following error on any call to rake. I am working on a Rails 3 running on JRuby (1.5.1) installed with RVM. I don't think this was always the case, but I'm not sure how to track it down. Am I correct in think this has something to do with the gems I have installed (listing included below)? $ rake metrics:all /Users/Eric/.rv...

We're running a small web application written JRuby on Rails running under Tomcat. We're using a Spring back-end that's shared with another production web application. Unfortunately, we keep running into PermGen problems. OS: Ubuntu Linux 2.6.24-24-server #1 SMP x86_64 GNU/Linux Java: 1.6.0_21 Tomcat: 6.0.28 JRuby: 1.5.0 Rails: 2.3.7 W...
I would like to develop some apps for the JVM using a concise, dynamic language. The most popular choices for this seem to be Jython, JRuby, Groovy, and maybe Clojure. Rhino appears to be fast and very stable, but I see no books on Rhino development and little discussion. Why is there apparently little use of JavaScript for other than e...
We're running a small JRuby on Rails app under Tomcat 6.0.28 with a Spring-based backend. I've spent some time with the Eclipse Memory Analysis tool and I can definitely tell that instances of the JRubyClassLoader are leaking. I setup our webapp to only use a single JRuby runtime and then I effectively did a hot-deploy to Tomcat by touch...
I am trying to deploy a jruby on rails application. Right now I am running mongrel + Apache2 using reverse proxy from mod_proxy. However, because mongrel_jcluster does not work for the latest versions of jruby, I am only able to run one mongrel server, and cant take advantage of load balancing from apache2. Is there any way other way ...

Using JRuby from RVM and the GlassFish Ruby gem. I haven't been able to reproduce this in other projects. However, in one project of mine, regardless of what's in the config.ru, if I run $ glassfish, then it loads up the server and the output is from when I first launched GlassFish many days ago, even if I uninstall and reinstall the ge...
What have you found as the best sources for jRuby interop syntax with Java? It took me forever yesterday to find something about adding to the classpath and the jruby.org site was not much help. Curious what references others use. Thanks. ...
Are there specific frameworks for Jython or JRuby, or is it you can run a py or ruby app on the JVM? i.e. you take your python django app, and you can run in on tomcat using jython? Sorry little confused. ...
Hi jruby mavens, I'm trying to install jruby gem from http://github.com/bpmcd/win32ole . it seems that standard jruby -S gem install win32ole doesn't work. I'm ruby noobie, and so far I understand that this package is not a gem? Am I correct? Do I need to build it? If yes, could you direct me to the docs that explain how to proceed...
I am using a class that accepts overridden methods i meant optional argument signatures (not sure if that matters in this case, but maybe) when I call this from IRB it is working as expected, eg, it accepts the arguments (filtering namespaces and passwords with [filtered] where needed to keep secret stuff secret and my company happy) ...

Background: I have a java library that is accessed by many developers - usually via java. However, a few devs hope to access this via a Ruby API. I am gravitating in the direction of Jruby in order to implement a Java-Ruby API. Questions: My main concern is that these developers will not be able to utilize the API in their current, R...
I have a simple question really: SWT documentation says that if you're using styledText, you either implements its API or you implement LineStyleListener. So, If I do use LineStyleListener, how can I still control the representation of specific characters in the editor widget? It seems that implementing LineStyleListener only provides c...
