What Eden said, additionally, your sample in the blog post will mostly work, but be careful of threading issues.  In Ruby it's not so bad, but in JRuby you can get hit with weird bugs because they use real threads.

For example, double check that the connection object you're using to query the SQL server doesn't need a little lock.
