logging errors with Rails logger

Coming from the java log4j world, the default logging functionality in rails seems a bit primitive to me, but it might have to do with my lack of knowledge on the subject. Currently I would log an exception like:

     begin
       //some code
     rescue Net::IMAP::ResponseError => exc
       Rails.logger.error("IMAP error for event #{@event.inspect}:\n #{exc.message}\n#{exc.backtrace.join("\n")}")
      end

The above code gets the job done in that i get a decently formated backtrace with an error message, but it is obviously not ideal. Also, my log file is missing valuable meta-data like time and the class which logged the message. Is there something I am missing?

thx.
