Default JDO ? ? - 01-08-2004 , 03:21 AM






HI
I want to use JDO to persistence objects to file system. Need to
buy a third-party persistence framework? or the javax.jdo already can
do?

thanks

Peter,

in order to use JDO, you will need a JDO implementation by
a third-party vendor.

A good place to look for one would be:
http://www.jdocentral.com

The website also has a forum for discussions around JDO and
just about all vendors and JDO experts read along:
http://www.jdocentral.com/forums/index.php

Kind regards,
Carl

Hi
Hard to find a JDO vendor that support mapping object to file system.
All of them support mapping object to JDBC only.
Would you like to give me a suggestion?

thanks

Hi guys,

I may be wrong but I thought Sun's reference implementation of the
JDO was strictly a filesystem based implementation. Meaning that
it doesn't us an RDBMS on the backend.

Yes, but would you use it for production?


Kind regards,

No, it's a reference implementation. Probably not fit for a production
environment,
but then again it all depends on the environment. Tomcat is a reference
implementation
too, but that doesn't seem to stop people from using it in production
environments.
