Method: Sequel::JDBC.load_driver

Defined in:
lib/sequel/adapters/jdbc.rb

.load_driver(drv, gem = nil) ⇒ Object

Attempt to load the JDBC driver class, which should be specified as a string containing the driver class name (which JRuby should autoload). Note that the string is evaled, so this method is not safe to call with untrusted input. Raise a Sequel::AdapterNotFound if evaluating the class name raises a NameError.
