title: DB2 Adapter for Ruby on Rails vs ActiveRecord JDBC Adapter
body: <p>Could anyone point to me the differences and the benefits between using "DB2 Adapter for Ruby on Rails" and "Active Record JDBC Adapter"?</p>
  
  <p>Generally, I am going to use the "jRUby on Rails" and "DB2 Express-C" and till now, I have thought the only way to connect IBM DB2 database with RoR application is using <a href="https://github.com/jruby/activerecord-jdbc-adapter" rel="nofollow">ActiveRecord JDBC Adapter</a>. </p>
  
  <p>Anyway on the <a href="http://www-01.ibm.com/software/data/db2/express-c/download.html" rel="nofollow">DB2 Express C</a> download page, there is a link to <a href="http://rubygems.org/gems/ibm_db" rel="nofollow">Rails Driver and Apdater for DB2</a> gem.</p>
  
  <p>Which one I should use?</p>
