The GenerationTool takes care of generating Java code from a database schema.

 It takes its configuration parameters from an XML file passed in either as a JAXB-annotated Configuration object, or from the file system when passed as an argument to main(String[]). 

See http://www.jooq.org/xsd/ for the
latest XSD specification.
