The JDBC adapter I've been working on for the Ruby DataMapper framework finally seems stable enough for a beta release... if anyone is interested please check it out. Basically it allows you to code in Ruby against the OpenEdge database, defining your database models as Ruby objects. Check out the "Querying" section and downwards for how to execute database statements from Ruby.
For now I've only tested it against 11.1 and 10.2B as that's what I've got... curious for any feedback if anyone wants to try it out.
Just published a follow-up post that demonstrates writing a RESTful JSON Web service for manipulating sports2000 customers in 51 lines of Ruby
Also fixed a bad build of one of the gems that was apparently throwing some weird error message on create statements.
