I use Jboss 4.2.2.G , Mysql 5.0 and entitybean 3.0. The problem I have is that the type of the object keeps tinyblob. I would want to change longblob but it does not work. Here is a code. public class Test implements Serializable { private static final long serialVersionUID = 1L; private Long id; @Lob @Column(name="cmd",columnDefinition="LONGBLOB",length=1000000) private Object cmd <-- this is always tinyblob. Does anyone know how to change to make longblob?. thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4159423#...
