Re: Java Persistence Architectures

If you are interested in Sun's JDO as I am, you may want to investigate TJDO for
future consideration (i.e., when it gets out of beta).

http://tjdo.sourceforge.net

I got a quick and dirty example running fairly easily.  I don't know if it works
in an EJB container (where I really would like to use it), though.

BTW, xdoclet has a subproduct called jdodoclet.
