do_jdbc 'Doppio'


Native JDBC Support for DataObjects.


do_jdbc is a gem wrapper for the common library that uses JDBC to support DO drivers running on the JRuby implementation.


This is a support library and should not be used directly.


  • JRuby 1.3.1 + (1.4+ recommended)
  • data_objects gem


To install the gem:

jruby -S gem install do_jdbc

Normally, you would not install do_jdbc directly. Instead it should be installed when installing DO drivers on JRuby, thanks to RubyGems dependency resolution.

To compile and install from source:

  • Install the Java Development Kit (provided if you are on a recent version of Mac OS X) from
  • Install a recent version of JRuby. Ensure jruby is in your PATH and/or you have configured the JRUBY_HOME environment variable to point to your JRuby installation.
  • Install data_objects with jruby -S rake install.
  • Install this driver with jruby -S rake install.
