I'd like to ignore the traditional mapping files, and use only the new annotation based entity mapping in my next hibernate project. I have checked hibernate org, and find an alpha release of hibernate annotations(and an ejb3 early acces lib inside). Do you think i could use this stuff right now for simple mappings, or wait until the new ejb spec evolve further? I'm pretty confused because the hibernate3 reference doesn't say a word of it, just shows the mapping file based approach. I would like to see a a real world working app based on the new technology. Could you show me one?
