Hello again. I'm trying to use a entity bean to maintain a table, but i want to truncate data if it's longer than column's table definition. The annotation i'm using in the entity bean is : @Column(name = "descripcion", length=100) private String descripcion; In theory, Jboss should truncate the data to 100 characters if longer, but it didnt. Jboss isnt truncating anything. I dont know if the attribute of length must be used for that, for size limitations or is intended for another thing. Thank you very much for your help.
