One-To-Many Relationship with Join Table

I have a one-to-many relationship modeled using join table:

create table t1 (id int primary key, name varchar(10) /*...*/);
create table t2 (id int primary key, name varchar(10) /*...*/);
create table t1_t2 (t1_id int, t2_id int, primary key (t1, t2));

The tables are supposed to model the relationship of one t1 to many t2. What is the right way to model these tables using JPA?
