org.apache.ws.jaxme.pm.xmldb.XmlDbPM
public class XmlDbPM
This is a persistence manager for the XML::DB interface. In other words, using this persistence manager you may read documents from a database via the XML::DB API or write them into the database using the same API.
This persistence manager is generic: The same manager works fine for any JAXB element.

public void select(Observer pObserver, java.lang.String pQuery, PMParams pPlaceHolderArgs) throws PMException
PM
Reads documents matching the given query. For any document matching, the Observer's notify method is executed with the matching document as an argument.
The query may contain placeholders. If it does, you have
to supply an instance of PMParams
with the placeholder

manager.select("Name = ? and Id = ?", new PMParams().addString("Someone").addInt(4));
pObserver
- This Observer is notified for any matching document.
The document is added as an argument.pQuery
- The query to perform. May contain placeholders.pPlaceHolderArgs
- An array of objects or null, if the
query doesn't contain any placeholders.
