JRuby JDBC-mysql error

Question

I have JRuby + Swing application and want to add jdbc/mysql there

require "jdbc/mysql"

But when I'm trying to run it, I have the followig error:

LoadError: no such file to load -- jdbc/mysql
  require at org/jruby/RubyKernel.java:1033
   (root) at olap_frontend.rb:3

My gem list:

*** LOCAL GEMS ***

activerecord-jdbc-adapter (1.2.2)
activerecord-jdbcmysql-adapter (1.2.2)
bouncy-castle-java (1.5.0146.1)
bundler (1.1.3 ruby)
jdbc-mysql (5.1.13)
jruby-launcher (1.0.12 java)
jruby-openssl (0.7.6.1)
rake (0.9.2, 0.8.7)
rubygems-bundler (0.3.0 ruby)

What I'm doing wrong?

LoadError: no such file to load -- active_record require at org/jruby/RubyKernel.java:1033 (root) at olap_frontend.rb:4 — skayred, Commented Apr 7, 2012 at 3:10

It was my fault - I need to require rubygems first

If anyone happens across this when using Ruby 1.9, this is only an issue in 1.8. 1.9 requires rubygems automatically.
