Carsten Hoehne commented on JBIDE-1768:
---------------------------------------

Hello, i have rechecked. When i deploy with the Annotation from the previous comment this exception is thrown:
14:24:52,125 ERROR [[/glimpse]] Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
javax.persistence.PersistenceException: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: de.bafz.lims.model.Sample2Well.sampleWell[de.bafz.lims.model.SampleWellType]
	at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:252)
	at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:120)
	at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:51)
	at org.jboss.seam.persistence.EntityManagerFactory.createEntityManagerFactory(EntityManagerFactory.java:85)
	at org.jboss.seam.persistence.EntityManagerFactory.startup(EntityManagerFactory.java:50)

That is correct, since SampleWell is not mapped.
I have come up with this annotation, which does deploy but i am not sure if this is the correct equivalent for the hbm.xml pcounterpart.

   @CollectionOfElements(fetch=FetchType.EAGER)
    @JoinTable(name="samplewell", joinColumns = { 
        @JoinColumn(name="SAMPLE2WELLID", nullable=false, updatable=false) }
)
    @Cascade( {CascadeType.SAVE_UPDATE} )
    public Collection<SampleWellType> getSampleWell() {
        return this.sampleWell;
    }

> Java code with annotations should be generated from a mapping file. This file contains a collection of components. Then an exception is thrown. See forum reference.
> The files will be attached.
