Re: Retrieving POJO using Native Query

[chintan4181]

We have this common code becuase we dont know entity defined in the
persistence.xml belongs to which persistent unit. so iterate over entity
managers to find out. Once we find out we assign entity manager and then
interact with db with that em.

//em1 we got it from emf map
Set<EntityType<?>> em1Entitites = em1.getMetamodel().getEntities();

Set<EntityType<?>> em2Entities = em2.getMetamodel().getEntities();

for (EntityType type : em1Entitites) {
        Class javaType = type.getJavaType();
//fnDO is passed entity       
if (javaType.getName().equals(fnDO.getClass().getName())) {
    em = em1;
    break;
}
}

for (EntityType type : em2Entities) {
        Class javaType = type.getJavaType();
        if (javaType.getName().equals(fnDO.getClass().getName())) {
                                                em = em2;
                                                break;
                                        }
                                }

Hope that will help to understand you more details.
