jaxb2ruby

https://github.com/sshaw/jaxb2ruby

jaxb2ruby generates Java XML mappings via xjc, reads the resulting annotations, and passes the extracted info to an ERB template. This allows one to automatically map an XML schema to pure Ruby classes (i.e. classes that don't require JRuby) using the mapping framework of their choice. Several templates are included: ROXML, HappyMapper and generic Ruby class (PORO).
