I’ve tried using JRuby with Rails 2.3.8 and Sql Server 2008 and
everything is smooth. But I’m facing some problems with Rails 3.
Here’s an error that I get when I try to find a post by id. However if I
find all the posts, i.e. ‘Post.find.all’ then it still works but
‘Post.find(1)’ generate the following error.
Is activerecord-jdbcmssql-adapter ready for Rails3?
Has anyone been able to use JRuby, Rails3 and Sql Server; any
recommendations?
Thanks
