[Java lista] Eclipse EJB + JPA

[Peter Olaj]

Sziasztok!

Van egy Eclipse workspace-em, benne egy Enterprise project. Alatta van külön egy EJB, egy JPA és egy WEB project. A JPA project-ben megvan a persistence.xml (1 unit van benne) és itt van egy ősosztály, amiben deklarálva van az 

@PersistenceContext
protected EntityManager em;

Ebből az ősosztályból származnak az EJB projectbeli Session Bean-ek.

Viszont valamiért nem akarja összepárosítani a unit-ot a context-el. Úgy sem, hogy megadom a unitName-ben a nevét.
Mit hagytam le és hol???
