jdbc - jRuby: use oracle database -

I try to make this simple MRI script work in jRuby but I get an error below I have the same gem in my MRI , I do not want to use active records JDBC, just make a simple connection and query, what should I do?

  C: \ jruby-1.7 4 \ bin & gt; JRuby gem list S --local   
 returns  
  .. ruby ​​oci8 (2.1.0 86-mingw32) ..   
 script  
  requires 'oci8' $ Conn = OCI8.new ('test', 'test', 'dbcm.cm_121') SQL =% Q {table Select * from $ conn.exec (sql) .fetch_hash do | R | R.each {| Key, value | "# {Key} is # {value}"} Finally puts $ conn.logoff   
 error  
  C: \ jruby-1.7 .4 \ test & gt; JRuby fetch_sql.rb LoadError: No such file to load - og8lib_jruby191 requires org / JRuby / RubyKernel.java: 1054 celsius is required: /jruby-1.7.4/lib/ruby/shared/ Rubygems / custom_require .rb: at 36 celsius (route): /jruby-1.7.4/lib/ruby/gems/shared/gems/ruby-oci8-2.1.0-x86-mingw32/lib/oci8.rb: 43 Org / requires JRuby / RubyKernel.java: 1054 (root) at C: /jruby-1.7.4/lib/ruby/shared/rubygems/custom_require.rb: 1 (root) at fetch_sql.rb: 1
