Force reload EntityManager

My problem are that my entityManager have my daabase in cache. This are a heavy problem because I´m doing a aplication prepared for many users and I cant show actual data.

public List<Tripulante> listxxx(String tip,
        String uni, String est, boolean val) {
    em.flush();
    Query q = em.createQuery("select");
    q.setParameter(dat1, uni);
    q.setParameter(dat2, est);
    q.setParameter(dat3, val);
    return q.getResultList();
}

I tried with em.clear to.

Im very lost with that I dont know I touch in persistence.xml or weblogic in jndi

I solve with that:

In persistence.xml i put that:

<property name="eclipselink.query-results-cache" value="false"/>

And in query that I doesnt wanna read in cache put that:

public List<Tripulante> listxxx(String tip,
    String uni, String est, boolean val) {
Query q = em.createQuery("select");
q.setHint("javax.persistence.cache.storeMode", "REFRESH");
q.setParameter(dat1, uni);
q.setParameter(dat2, est);
q.setParameter(dat3, val);
return q.getResultList();

}
