[jboss-user] [EJB 3.0] - a little prombel about using EJB3.0

i met a promble when i was using EJB3.0. i'd like to search a part of values from the table, so i used em.createNativeQuery() and the sql statement is "select cifno,cifname,idnum from cr_personinfo where rownum <50". but it can not run properly .here is the error message: "can not read column value from result set" so i change the sql statement "select * cr_personinfo where rownum <50" it can run properly . why ? thanks!
