Why and how to use or not to use JRuby

• Desired talk duration: 30 minutes

Abstract

In recent years JRuby is becoming more mature as well as more popular Ruby implementation. But still JRuby typically is not the default choice for new Ruby on Rails applications as Ruby developers are just more familiar with MRI. In this talk practical advice will be given why and how to use JRuby in Rails applications as well as when it might not be the best solution:

• Why to use - speed, multi-threading, re-use of Java libraries
• Why not to use - multiple processes, slower start-up, some C extensions
• Setting up development environment
• Simple and more advanced Java libraries integration
• Sessions, caching, message queues, background and periodic jobs
• Debugging, monitoring and troubleshooting
• Application servers and deployment options
• Packaging and distributing standalone applications

Notes

Author has used extensively JRuby to build eazyBI application and presented advice is based on experience during building this and other JRuby based applications.
