know of any open source object-relational mapping classes?

[Gennady Ioffe <GI...@scient.com>]

Hi everyone!

Many people that use tomcat on this list also probably need to find a good
way to simplify dealing with database access.

Can somebody who's gone through this share comments or their experience:
 -are there any good object-relational mapping classes available, open
source if possible?
 -where can i find a set of classes to generate java beans from an existing
set of relational db tables?

so far I know that: 
turbine project has a set of database connection pooling classes.
town (http://www.working-dogs.com/town/) seems like a JDBC api that does OR
mapping an connection pooling.

thanks for you comments or pointers,
gennady ioffe

DbGen just became open source and I am the project admin.  See

Also the Exolabs (sorry can't find the URL) guys (or Assaf Arkin from memory) has developed the Castor library which performs O->R mapping, though haven't used it myself. You can possibly also look at the JAWS code in http://www.jboss.org though the O-R used in this is specific to EJB.

Joe

I haven't used it and can't really recommend it, but the Enhydra project has
a tool to do this called DODS:

good luck.
