Map Struts tag s:checkboxlist by Hibernate?

Question

Hello all,

How to map Struts tag s:checkboxlist by Hibernate?

For example, in the following I know company field in auth.hbm.xml is wrong. How do I correct this? Thanks!

Model:

String a[]={"browse","add","delete","update"};
boolean company[]=new boolean[a.length];

JSP:

<s:checkboxlist name="auth.company" list="%{auth.a}" key="company"/>

auth.hbm.xml:

<property name="company" type="int" not-null="true" />

MySql:

drop table if exists auth;
CREATE TABLE auth 
(
id int unsigned not null auto_increment,
name text not null,
company int unsigned not null,
enabled boolean not null default true,
PRIMARY KEY (id),
UNIQUE KEY id (id)
)type=innodb;
