[EJB 3.0] - Customizing the persistence of an embedded object
by SmokingAPipe
Simple question: I have a class that uses an embedded object that's not an entity, like this:
| @Entity
| public class LogMessage {
| private java.util.logging.Level level;
| }
|
Right now, the way that handles it is it creates a bytea column to store the level. Of course that's not what I want. What would be ideal would be to somehow annotate it so I could define my own persistence for that particular field. In this case, I would want to persist it as either an integer or a string perhaps. I know in Hibernate it wasn't a big deal to write my own custom type with its own storage approach but I can't find anything like that in EJB3. Any ideas?
Of course the other thing i can do is to just write up my own enum and not even use the java.util.logging.Level class, but hey, that class is there and does exactly what I want so it would be ideal to use it.
Thanks for any ideas on this

[EJB 3.0] - ClassCastException EJB3 wrapped local object.
by hurzeler
Hello there,
I have the following issue. I have a Stateless session bean called SiteDAOBean. This bean has a method:
| public void update(Site site) throws PersistenceException
| {
| em.merge(site);
| }
|
Which works nicely if I call it remotely with a Site argument. However due to some extra functionallity that I need locally I have to wrap the Site class by extending it to SelectableSite. It then has a couple more methods that are only used locally and a field that is transient but it is still fundamentally a Site class.
Calling:
| SiteDAO siteDAO = (SiteDAO) context.lookup(SiteDAOBean.class
| .getSimpleName()
| + "/remote");
| siteDAO.update(site);
|
I get the following exception:
Caused by: java.lang.ClassNotFoundException: No ClassLoaders found for: mhl.edm.util.SelectableSite (no security manager: RMI class loader disabled)

Obviously I need to cast the SelectableSite back to Site so that RMI does not complain not finding the class remotely.
I tried:
siteDAO.update((Site)site);
but that does not work. Can anyone tell me how to overcome this issue short from creating a new Site object?
Thanks for your help.
