Definitely never write BMP entity beans from scratch.
We've built a pretty cool little framework for generating our BMP beans from
UML Class models; but there are tons of open source tools to generate beans;
percolator, ejbwizard, ejbcreator, Cedric Beust has posted his to this list,
Rickard Oberg has ejbdoclet, I'm sure there are more, then there are all the
commercial ones like CocoBase or Toplink, plus all the open source O/R
frameworks like CastorJDO. Loads of choices.
Cheers

True, I've done my own fiddleing and have written plenty of my own code
that hardcodes everything.

Or do BMP with CastorJDO.
