Re: [Exist-open] Persistence Layer like OJB/Hibernate for working with eXist?

[Timothy W. <tim...@ya...>]

Hey Christoph, I'm in need of exactly the tool you are
describing. Back in July, I posted to find out if
there was a java transparent persistence library for
xml Databases. XMLBeans and JAXMe(JaxB) don't really
do what you are looking for - which is transparent
persistence to a native xml database. What I find
doesn't work is the mapping between xml and relational
table. There was nothing really out there at the time,
but the community was willing to help develop such a
tool - I think there's a big demand for it. When my
time frees up in the new year. I'm certainly willing
to contribute to such a project.
