GlashFish V3 前两天刚除了预发行版本，今天 JRuby 推出了为其定制的版本。

安装方法
============

gem install glassfish

新的特性
============
* Based on GlassFish v3 Prelude nucleus
o GlassFish v3 Prelude is a production quality application server and the nucleus is based on this final version.
* Rack based
o GlassFish gem is Rack based. This means it would be pretty easy to add any Ruby based web frameworks, such as Merb, Camping, Sinatra, etc.
* Merb support
o Not just Rails, you can start running your Merb applications, simply type glassfish in your Merb application directory.
* Autodetection of application framework
o Simply type glassfish and it will detect what app you are running, whether Rails or Merb
o It means you have to know about only one command glassfish. glassfish_rails is deprected and supported for now due to backward compatibility
* -port or -p option to specify on which port your application runs
* -environment or -e option to specify the Rails development environment, such as production, development or test
* JRuby runtime pool configuration
o Much needed for scaling when running Rails 2.1.x applications
o Not required if running Edge Rails (2.2). Because it is supposed to be MT or atleast MT safe.
o Also, not required for Merb
