Source of the called function

public int createStatus(StatusAdapter adapter) {

Query query = em.createQuery("SELECT OBJECT(s) FROM Status s WHERE s.name=?1")
.setParameter(1, adapter.getName())
.setMaxResults(1);
if (query.getResultList().size()>0) return JBFinals.STATUS_NAM_ERR;

Status status = new Status();
status.setName(adapter.getName());
em.persist(status);
adapter.setId(status.getId());
return JBFinals.PERSIST_OK;
}


Configuration in the persistence.xml file


<?xml version="1.0" encoding="UTF-8"?>


<entity-manager>
JobBoerseEM

... jbserver.jbbusiness.jbpersistence.Status

...



<!--create-drop--><!--org.hibernate.dialect.MySQLDialect-->


</entity-manager>


It is quite urgent to solve the problem and we have no idea.
