Is there any way to get JPA to map a String member variable as a 'char' sql data type instead of the default 'varchar'? In an EJB3 Entity Bean I have the following member variable defined: ... @Column( name="STATE", nullable=false, length=2 ) private String state; ... When using JPA to read/persist this entity, using Hibernate as the provider, I get an exception complaining that varchar(2) was the expected type for the column. I don't want to have to modify the database schema to varchar(2) even though that is trivial. My only guess is that I need to use the "columnDefinition" attribute of the @Column annotation. Thanks in advance. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4139485#...
