[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Mysterious difference of mapping on Integer on windows an Bi

Hi, I have a jboss4.2.2, which run under windows for dev and linux for production. All my jboss configurations files are same under linux (unbuntu) or windows. I ve a strange difference My EJB is with a int field; I use a query ( Query q = em.createNativeQuery(request);) Under windows I get my field as this photoId=((Integer) rs[8]).intValue(); But it doesnt works under linux and i need to get a BigInteger. photoId=((java.math.BigInteger)rs[8]).intValue(); So temporarly i do: if(rs[8] instanceof java.math.BigInteger){ | photoId=((java.math.BigInteger)rs[8]).intValue(); | }else{ | photoId=((Integer) rs[8]).intValue(); | } There is anybody who have an idea?
