Hi All,
I am trying to write a bunch of tests with JUNIT for my JDO classes.
The package works when integrated in a appengine web application, but
I get a RunTimeException when testing in a Junit 'environment'.
I started with the JDODataSourceConfigTest source file in the
appengine test directory.
and It's ok with nothing included.
Then I tried to store some data within the two methods implemented:
public void testTransactionalPMF() {
JDOPersistenceManagerFactory pmf = (JDOPersistenceManagerFactory)
JDOHelper
.getPersistenceManagerFactory("transactional");
DatastoreManager storeMgr = (DatastoreManager) pmf.getStoreManager
();
JDOPersistenceManager pm = (JDOPersistenceManager)
pmf.getPersistenceManager();
// assertTrue(storeMgr.connectionFactoryIsTransactional());
DomainGAE domain = new DomainGAE("Name", "Description");
Transaction tx = pm.currentTransaction();
try {
tx.begin();
pm.makePersistent(domain);
tx.commit();
} catch (Exception e) {
System.out.println("Exception e: " + e);
e.printStackTrace();
if (tx != null) {
tx.rollback();
}
}
pm.close();
pmf.close();
}
-------------------------------
DomainGAE is a simple Class
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
import com.google.appengine.api.datastore.Key;
import com.google.appengine.api.datastore.KeyFactory;
import ....
@PersistenceCapable(table = "domain", detachable = "true")
public class DomainGAE implements Domain {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
protected String name = null;
protected String description = null;
public DomainGAE(String name, String description) {
this.name = name;
this.description = description;
}
.....
}
Here is the error and the stackTrace:
Exception e: java.lang.RuntimeException: Unable to replace
JPACallbackHandler.

I did the test with maven and also directly with junit by providing
the lib from 1.2.8
Results are the same.
I tried to extends JDODataSourceConfigTest from LocalServiceTestCase
or LocalDatastoreTestCase (http://code.google.com/appengine/docs/java/
howto/unittesting.html)
but I got the same error.
I am sure I forgot something, but I can't figure what.
Does anyone has an hint?
Thanks
