Hi Gokmen,
Enhancement for clearing the design time errors by providing support for xsi:type is planned for the Shepherd release.
The workaround for the Connection Pool errors is to define using the API.Below sample code can be useful for you.
Create a class which implements SessionEventListener or extend SessionEventAdapter and override the preLogin(SessionEvent event) and define read and write connections in the method.Register the SessionEventListener with session(open the session.xml in JDeveloper flat editor->Options->EventListener->browse and Select the class).
When application is run and preLogin() event will be called and connection pool is defined with read and write connections.
package model;
import org.eclipse.persistence.sessions.SessionEvent;
import org.eclipse.persistence.sessions.SessionEventAdapter;
public class SampleEventListener extends SessionEventAdapter {
public SampleEventListener() {
super();
public void preLogin(SessionEvent event) {
System.out.println("in the pre login method");
org.eclipse.persistence.sessions.server.ServerSession serverSession=(org.eclipse.persistence.sessions.server.ServerSession)event.getSession();
serverSession.addConnectionPool("testReadPool", event.getSession().getDatasourceLogin(), 1, 10);
public void postLogin(SessionEvent event) {
org.eclipse.persistence.sessions.server.ServerSession serverSession=(org.eclipse.persistence.sessions.server.ServerSession)event.getSession();
System.out.println(serverSession.getConnectionPool("testReadPool").getMaxNumberOfConnections());
System.out.println(serverSession.getConnectionPool("testReadPool").getMinNumberOfConnections());
Hope this helps.
