What steps will reproduce the problem? 1. Run the sequel command with an Oracle JDBC URL: sequel jdbc:oracle:thin:user/password@host:1521:instance

What is the expected output? What do you see instead?

Should connect to the database (if available). Instead, there's an oracle method error.

What version of the product are you using? On what operating system?

Version 2.5 but still an issue with 2.6

Please provide any additional information below.

JRuby automatically assumes any references starting with com., java., etc. are Java references. But oracle. is not one of the the supported prefixes. The fix is to prepend Java:: to the oracle JDBC driver class name in jdbc.rb.

Fixed: http://github.com/jeremyevans/sequel/commit/323e218f024dc98c61dd04d1a40d037a7bd85794

Also, now that it is apparent that someone is actually using Oracle via JDBC, I split the oracle adapter into shared and unshared parts, for better support for Oracle when accessed via JDBC (http://github.com/jeremyevans/sequel/commit/13008199c1ea7690b4dcf752aa3fe4a8134e296f). If you could test this support, I would appreciate it. I'm not able to test it as I don't have access to an Oracle database.
