First approach: bare metal
require 'java'
require 'rubygems'
require "c:/ruby/jruby-1.2.0/lib/ojdbc14.jar" # should be redundant, but tried it anyway
odriver = Java::JavaClass.for_name("oracle.jdbc.driver.OracleDriver")
puts odriver.java_class
url = "jdbc:oracle:thin:@myhost:1521:mydb"
puts "About to connect..."
con = java.sql.DriverManager.getConnection(url, "myuser", "mypassword");
if con
puts " connection good"
else
puts " connection failed"
end
The result of the above is:
sqltest.rb:4: cannot load Java class oracle.jdbc.driver.OracleDriver (NameError)
Second approach: Active Record
require 'rubygems'
gem 'ActiveRecord-JDBC'
require 'jdbc_adapter'
require 'active_record'
require 'active_record/version'
require "c:/ruby/jruby-1.2.0/lib/ojdbc14.jar" # should be redundant...
ActiveRecord::Base.establish_connection(
:adapter => 'jdbc',
:driver => 'oracle.jdbc.driver.OracleDriver',
:url => 'jdbc:oracle:thin:@myhost:1521:mydb',
:username=>'myuser',
:password=>'mypassword'
)
ActiveRecord::Base.connection.execute("SELECT * FROM mytable")
The result of this is:
C:/ruby/jruby-1.2.0/lib/ruby/gems/1.8/gems/activerecord-jdbc-adapter-0.9.1/lib/active_recordconnection_adapters/jdbc_adapter.rb:330:in `initialize':
The driver encountered an error: cannot load Java class oracle.jdbc.driver.OracleDriver (RuntimeError)
Essentially the same error no matter how I go about it.
I'm using JRuby 1.2.0 and I have ojdbc14.jar in my JRuby lib directory
Gems:
ActiveRecord-JDBC (0.5)
activerecord-jdbc-adapter (0.9.1)
activerecord (2.2.2)
What am I missing?
Thanks,
