Hi guys, I'm trying to execute a simple native query using JBoss 4.0.5GA and EJB 3.0. Here is my entity bean with the SqlResultSetMapping annotation: @SqlResultSetMapping(name="poiResultsMapping", | entities=(a)EntityResult(entityClass=POI.class, | fields=@FieldResult(name="name", column="POI_NAME"))) | @Entity | public class POI implements java.io.Serializable { ... } Here is the native query which fails in the session bean. | q = em.createNativeQuery("select p.POI_NAME from poi as p limit 8", "poiResultsMapping"); | | this.poiResults = q.getResultList(); | This is the cause of the error : 2007-09-17 13:36:53,608 INFO [org.hibernate.type.LongType] could not read column value from result set: POI2_12_0_; Do you see what could be wrong with this code ? Did I forget something ? Regards. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4085040#...
