Hallo,

we have a problem creating tables using JBoss 4.0.3 SP1, MySQL 4.1.13 on Solaris .

Following exception occurs

Source of the called funktion

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

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