[appengine-java] makePersistent() question

[Pion]

I am using App Engine SDK 1.2.5 with Eclipse-Galileo on Windows Vista
with the following (simplified/stripped) code:

import javax.jdo.annotations.IdentityType;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;

@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class FooDb {
    @PrimaryKey
    @Persistent
        private String id;

    @Persistent
    private String name;

        public FoafIndexDb(String id, String name) {
                this.id = id;
                this.name = name;
        }
}

//////////////////////////////////////////////////////////////////////

import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManagerFactory;

public final class PMF {

    public static PersistenceManagerFactory get() {
        return pmfInstance;
    }

    private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory("transactions-optional");

}

//////////////////////////////////////////////////////////////////////

PersistenceManager pm = PMF.get().getPersistenceManager();
FooDb fooDb = new FooDb ("key", "name");
try {
        pm.makePersistent(foafIndexDb);
} finally {
        pm.close();
}

//////////////////////////////////////////////////////////////////////

The output from DataNucleus Enhancement during build:

DataNucleus Enhancer (version 1.1.4) : Enhancement of classes
DataNucleus Enhancer completed with success for 1 classes. Timings :
input=147 ms, enhance=29 ms, total=176 ms. Consult the log for full
details

The output during execution:

601 [btpool0-3] DEBUG DataNucleus.Reachability  - Completed check of
objects for "persistence-by-reachability" (commit).

THE PROBLEM: No (data) file created after running the above.

war\WEB-INF\appengine-generated\ folder only has datastore-indexes-
auto.xml which contains the following:

<!-- Indices written at Wed, 16 Sep 2009 17:58:16 UTC -->
<datastore-indexes/>

I am new on this. What did I miss?

Thanks in advance for your help.
