and I tried to change the code a little bit, but:
Caused by: Exception [EclipseLink-6007] (Eclipse Persistence Services
- 2.0.0.v20091127-r5931):
org.eclipse.persistence.exceptions.QueryException
Exception Description: Missing descriptor for [class
com.kenai.puj.arena.model.entity.PujInstitutionEntity].
the code:
ExpressionBuilder builder = new ExpressionBuilder();
ReadAllQuery query = new ReadAllQuery(PujInstitutionEntity.class,
builder);
Query dbQuery = ((JpaEntityManager) manager.getDelegate())
.createQuery(query);
institutions = dbQuery.getResultList();
