[jboss-user] [EJB 3.0] - One-To-One?how to make two tables share their primary key?

you see,in Hibernate,we can set a pojo to have an one-to-one relationship with the other entity by share their primary key,for example: | <class name="TUser" | table="user" | ...... | <one-to-one name="passport" | class="TPassport" | cascade="all" | outer-join="all" | /> | </class> | It is related with TPassport like: | <class name="TPassport" | table="user" | > | <id name="id" column="id"> | <generator class="foreign"> | <param name="property>user</param> | </generator> | </id> | <one-to-one name="user" | class="TUser" | contrained="true" /> | the TPassport's primary key is genearted by TUser's,how to do that in ejb3?I tried many times,but failed.who can give me an example?thanks!
