How the Ecore dynamic model with cdos, saved to the database, thank you？？？？

// Create the Workflow Package
EPackage workflowPackage = EcoreFactory.eINSTANCE.createEPackage();
//create the Port class
EClass portClass = EcoreFactory.eINSTANCE.createEClass();
portClass.setName("Port");
EClass inputPortClass = EcoreFactory.eINSTANCE.createEClass();
inputPortClass.setName("InputPort");
//set up inheritance
inputPortClass.getESuperTypes().add(portClass);
//create the Task class
EClass taskClass = EcoreFactory.eINSTANCE.createEClass();
taskClass.setName("Task");

// add name attribute to Task
EAttribute taskNameAttr = EcoreFactory.eINSTANCE.createEAttribute();
taskNameAttr.setName("name");
taskNameAttr.setEType(EcorePackage.eINSTANCE.getEString());
taskClass.getEAttributes().add(taskNameAttr);
// set up the reference between Task and InputPort
EReference taskToInputPortRef = EcoreFactory.eINSTANCE.createEReference();
taskToInputPortRef.setUpperBound(-1);
taskToInputPortRef.setLowerBound(1);
taskToInputPortRef.setEType(inputPortClass);
taskClass.getEReferences().add(taskToInputPortRef);
// add the classes to the package
workflowPackage.getEClassifiers().add(taskClass);
workflowPackage.getEClassifiers().add(portClass);
workflowPackage.getEClassifiers().add(inputPortClass);

EFactory wfFactory = workflowPackage.getEFactoryInstance();
final EObject task1 = wfFactory.create(taskClass);
task1.eSet(taskNameAttr, "Task1");

final CDOSession session = openSession();
final CDOTransaction transaction = session.openTransaction();
// get/create a resource
//CDOResource resource = transaction.getOrCreateResource("/res2"); //$NON-NLS-1$

session.getPackageRegistry().putEPackage(workflowPackage);

// clear any previous data
//resource.getContents().clear();
//resource.getContents().add(task1);

transaction.commit();

ECORE dynamic model not persisted to the database,What reason be? thank you!!!
