Re: [eclipselink-users] GFv3 + EclipseLink >=2.1.1: Remote EJB client cannot transfer JPA entities through remote session bean

One other thing for either you, or the GlassFish folks.

Are the classes weaved on both sides? i.e. Are you sending a weaved class to somewhere where the class is unweaved, or vice versa?

We should be able to narrow down which component of our weaving causes the problem - and at the same time potentially find a workaround.

Reenable weaving and try turning of the various components of weaving and see which one causes the problem.

Try each of these:

eclipselink.weaving.internal=false
eclipselink.weaving.lazy=false
eclipselink.weaving.changetracking=false
eclipselink.weaving.fetchgroups=false

Yes, I am also tracking this in GF user list.

The stacktrace says nothing regarding EclipseLink but I think the problem is related to it because of a weaving issue.

The only thing I can think of in EclipseLink that could cause marshalling exceptions is our weaving. Try setting the persistence unit property eclipselink.weaving to false. If that helps, it will give us somewhere to
start looking.

Yes!, when I disable weaving with: ... <property name="eclipselink.weaving" value="false"/> .... in persistence.xml the problem stops.

Adding a entity class in persistence.xml (plus weaving enabled) as:
   ...
   <class>com.xxx.xxx.model._2.jpa.Unlocodes</class>
   ...
makes that class "untransferable" by remote EJB.

Curious is that the remote client can retreive a entity class using remote ejb method, but can't send the entity to the server (the problem is just in one direction), for example:

...
Properties props = new Properties();
props.setProperty("org.omg.CORBA.ORBInitialHost", "zeus");
props.setProperty("org.omg.CORBA.ORBInitialPort", "55537");
InitialContext ic = new InitialContext(props);
ServiceBeanRemote sb = (ServiceBeanRemote) ic.lookup(
ServiceBeanRemote.class.getCanonicalName());


        // This will work:
            Unlocodes entityInstance = sb.find(Unlocodes.class, "USMIA");

            // This won't work !!!
            sb.send(entityInstance);
   ...

As I said before with weaving disabled the problem don't occur and the entity instace got transferred.

Regards.
Xavier.
