问题
is there any particular way to convert a Ruby on Rails project to a JRuby on Rails project? There now is a need to get the Rails side to talk to a Java server via RMI so was wondering how to make the conversion. Thanks.
回答1:
As @Karl says, it pretty much works but there are a number of caveats you should be aware of:
- The database adapters will be different from the ones you may be used to. They're based on JDBC. For example, the MySQL adapter install is described here
- You will generally deploy to Java application servers in production such as Glassfish, Tomcat or Jetty. Typically this is done using Warbler
- Certain gems with native extensions may not work. See here for details on the what is required

It pretty much just works, you simply run it with JRuby instead of Ruby.
