Here at imediation we developped an XML based web application, and we find very difficult to do a _good_ DB mapping. Basically you can easily find a JDBC/XML mapping to translate a table into XML but when it comes to more sophisticated mapping, we could not see anything good. For instance expressing entire query in "pure" xml (ie without embedeed sql statement in xml doc) with joins, expressing insert/update query, whatever. So we developped our own but this is not efficient, as this is not standard. Any pointer/ideas about generic/powerful XML/SQL mapping, or incoming standard about that ?
