JDO with Datanucleaus

Datanucleaus access platform is an excellent Java OR mapping framework. It supports a lot of backends. I have been playing with Datanucleaus access platform 1.6. Here are some tricks I want to share.

 

EnhancerTask and SchemaToolTask all require that jdo configuration file such as package.jdo and jdo POJO classes can be found in classpath specified with classpathref attribute. JDO POJO classes must be found in dir attribute or nested fileset.
