public class DBWSModel
extends org.eclipse.persistence.internal.xr.XRServiceModel
PUBLIC: model object for eclipselink-dbws.xml descriptor file. A DBWS (also known as
an XRServiceAdapter) requires the following resources:
eclipselink-dbws.xml in the
META-INF/ directory.jar file, as an external 'exploded' directory on the classpath.war file)..xsd) file called eclipselink-dbws-schema.xsd.jar file, at the root of the first directory on theWEB-INF/wsdl/ directory of a .war file
sessions.xml file called eclipselink-dbws-sessions.xml (in the
META-INF/ directory)sessions.xml files can be overridden by the<sessions-file> entry in the eclipselink-dbws.xml
descriptor file.
Project
(either deployment XML locatedMETA-INF/ directory or Java classes on the classpath or in theWEB-INF/classes directory inside a .war file).A typical DBWS requires two projects: one to represent the O-R side, the other to
represent the O-X side.
The O-R and O-X Projects metadata must have:
i) identical case-sensitive Project names:
<?xml version="1.0" encoding="UTF-8"?>
<eclipselink:object-persistence version="Eclipse Persistence Services ..."
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

>
<eclipselink:name>example</eclipselink:name>
or
...
import org.eclipse.persistence.sessions.Project;
public class SomeORProject extends Project {
public SomeORProject () {
setName("Example");
...
}
public class SomeOXProject extends Project {
public SomeOXProject () {

...
}
ii) identical case-sensitive aliases for Descriptors
that are common between the projects:
