spring - Hibernate Mysql mapping relationship -

i'm not sure if possible in spring 3 framework using hibernate , mysql appreciate help. have 2 classes - employee , examiner. examiner employee , employee examiner. @ same time each examiner can examine 1 or more employees , employee can have 1 examiner.

basically want know if possible show inheritance between employee , examiner, , @ same time map unidirectional 1 many examiner employee?

what have far - examiner table inheritance constraint:

create table `examiner` ( `employee_id` varchar(255) not null, `employee_name` varchar(255) not null,  primary key (`enployee_id`),  foreign key (`employee_id`) references `employee` (`employee_id`)):  

the employee table:

 create table `employee` ( `employee_id` varchar(255) not null, `employee_name` varchar(255) default null, primary key (`employee_id`)): 

i thinking of join table showing 1 many behaviour getting compsite key table not possible have primarykeyjoin column.

i appreciate in pulling have been stumped days.

java doesn't allow multiple inheritance, unless using interface not sure how plan make 2 described classes instances of each other.

you make class called employeeexaminer, , make reference itself. annotations might like:

@entity public class employeeexaminer {   @manytoone   private employeeexaminer getexaminer() {/*...*/}    @onetomany   private list<employeeexaminer> getemployees() { /*...*/} } 

documentation on annotations can found here.
