Jozef, for the Castor JDO part of things, I recommend looking at
http://castor.exolab.org/jdo.html (use of castor jdo in general) and http://castor.exolab.org/jdo-mapping.html (JDO mapping) for introductions on how to use Castor JDO in general, and how to create a mapping file related to persisting (existing) object hierarchies. In addition, there's a complete set of samples included with Castor JDO that showcase a couple of scenarios, incl. 1:1, 1:m relationships, extends, etc. I hope this gets you started Werner On Thu, 26 Feb 2004 15:32:51 +0000, Jozef Aerts - Comp.Chem.Cons. - XML4Pharma wrote: > >Dear all, > >I have an XML file with data that have to go to a relational database. >The XML file looks like: > ><person name="Alice"> > <bonus date="2004-01-12" amount="100"/> > <bonus date="2004-01-24" amount="50"/> > <bonus date="2004-02-22" amount="120"/> ></person> ><person name="Jerry"> > <bonus date="2004-02-03" amount="70"/> ></person> > >The relational DB has a table "bonusses" with fields (columns): >personname, bonusdate, bonusamount > >So the table would look like: > >personname bonusdate bonusamount >------------------ --------------- ------------------- >Alice 2004-01-12 100 >Alice 2004-01-24 50 >Alice 2004-02-22 120 >Jerry 2004-02-03 70 > >Using Castor, I generated Java classes from the XML-Schema >and now am wondering how the mapping.xml should look like. > >Can anybody help me ? > >Sincerely > >Jozef Aerts > >_________________________________________________________________ >Play online games with your friends with MSN Messenger >http://messenger.msn.nl/ > >----------------------------------------------------------- >If you wish to unsubscribe from this mailing, send mail to >[EMAIL PROTECTED] with a subject of: > unsubscribe castor-dev > ----------------------------------------------------------- If you wish to unsubscribe from this mailing, send mail to [EMAIL PROTECTED] with a subject of: unsubscribe castor-dev
