RE: PostGIS - hibernate - EJB3

hi,  I am trying to use custom UserType, but it work fine in a pure Hibernate implementation , but not in JBOSS EJB3, the generated geometry column in postgres is of type "oid" instead of "geometry"    You have any suggestion, i am using jboss-EJB-3.0_RC8-FD and postgis 1.1.3 (on postgres 8.1.4)    

thanks.
