My Entity beans are not saved (stored) on data base

[Neo tnt]

Hi,

I work with Ejb2.1, oc4j et xdoctlet.
I have a problem with my entity beans CMP:

Context ctx = new InitialContext(properties);
       Object objref = ctx.lookup ("My");
           home = (MyHome) PortableRemoteObject.narrow ( objref, MyHome.class ) ;
home.create(BigDecimal.valueOf(5), BigDecimal.valueOf(54));
 

In this case my bean is created and i can manipulate it but it is not stored on data base.

if i look up for an id in the data base i got this exception

javax.ejb.ObjectNotFoundException: Exception [EJB - 10008] : bean de type [My] introuvable via la recherche [findByPrimaryKey].
at oracle.toplink.internal.ejb.cmp.EJBExceptionFactory.objectNotFound(EJBExceptionFactory.java:325)
	at oracle.toplink.internal.ejb.cmp.finders.Finder.checkNullResult(Finder.java:224)

	at oracle.toplink.internal.ejb.cmp.finders.FinderManager.findByPrimaryKey(FinderManager.java:125)

Here is what it tries to do:

1) Create a bean
2) Find it by primary key
3) Find all beans of that type by primary key
4) Remove all beans of that type by primary key

Here's what happens:

1) Bean is created
2) Bean cannot be found by primary key
3) findAll() returns a Collection of size 0
4) Nothing to remove

Now, if I try to create the bean again, I get an
exception because it's already there. But I can't find
it. So, next step:

1) Is anything is the database?

Answer: no. No database entries have been made. The
database is 100% empty.

This leads me to the conclusion that Entity bean is in
cache but not in the database and that the finders are
looking in the database.
