DAO and DTO Generation

["Christopher R. Gardner" <crgardner@charter.net>]

Any suggestions for tools that generate data access objects and data
transfer objects?  I'm interested in tools that ideally

* don't make your business objects inherit from a framework base class
* are priced right (e.g., not the price of a CocoaBase)
* are easy to use
* can examine a database schema to generate the code

I've looked a little at Torque.  I think it makes you inherit from a framework
base class.  Also, I don't know how reliable it is (especially running in a
Weblogic EJB container).  I've heard that Castor has lots of bugs.  JDO is still
too new.  TopLink I think is priced high.  OJB (another jakarta product) is in
an early release.  I feel like I'm running out of pre-built  options and I don't
have time to write my own.  Any comments on some of the products I've named (and
others)?

Thank you.
