[JBoss-user] [Persistence, JBoss/CMP, Hibernate, Database] - @OneToMany fails with FetchType.LAZY
Hi there, everytime I try to fetch a OneToMany-Mapped collection of the type list it fails. By invoking the customer's getEmails() method, I get the following exception which I don't understand really. Maybe someone of you can help me with that.

[JBoss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Problems with em.persist() and query.getResultList()
Hi there,
I'm using JBoss 4.0.3 SP1 and implemented a Service-Bean for initializing my
database with some data to play with. Everytime I execute a query within this
Bean, i get a is not mapped ... exception.
How is this persist()-method working? I thought that the data is directly
written to the database when it's invoked. I also tested to invoke the
flush()-method after invoking persist() but this didn't help either.
And here is the code.
| @Service
| public class StartupBean implements Serializable {
|
| @PersistenceContext(unitName = myem)
| protected EntityManager manager;
|
| public void start() throws Exception {
|
| // ...above are some initializations that work.
|
| contract = new Contract(product, 1.3.2006 12:00, null, null,
customerAccount);
| manager.persist(contract);
|
| // ...the following query throws an exception:
|
| query = manager.createQuery(SELECT c FROM contract c);
| query.getResultList();
|
| }
|
| }

[JBoss-user] [Persistence,JBoss/CMP, Hibernate, Database] - Re: Which version of Hibernate is my JBoss running?
A better way to get the version from your hibernate libraries shipped with the jboss is to look into the right JARs. Below the META-INF directory you'll find the version string in the MANIFEST.MF file.
