[jboss-user] [Beginners Corner] - Unable to load to deserialize result

Hi all, I store attachments file (like jpg, bmp, doc, pdf) inside a db table (postgresql db, column type is BYTEA). Insert is performed via a Stateful SessionBean that uses an Entity Bean. (at Entity Level the db column is mapped using the generic Object class). Insert is ok. When I try to read the attachments I use a Stateless SessioBean that calls a DAO Class (inside DAO Class, JDBC code: "select column from table ...." then I apply resulSet.getObject() method). Reading is ok. But when I try to remove the attachment (EntityBean remove() method) I get a strange exception. | ERROR [org.jboss.ejb.plugins.LogInterceptor] TransactionRolledbackLocalException in method: public abstract void javax.ejb.EJBLocalObject.remove() throws javax.ejb.RemoveException,javax.ejb.EJBException, causedBy: | java.sql.SQLException: Unable to load to deserialize result: java.io.StreamCorruptedException: invalid stream header | I think it's something related to serialization. Object class is not the proper class I must use to map a BYTEA DB column ? I use JBOSS 3.2.3 and Postgesql 7.4.5. Any help is very very appreciated. Thank you for your help.
