Storing a Map<String,String> using JPA

I am wondering if it is possible using annotations to persist the attributes map in the following class using JPA2

public class Example {
    long id;
    // ....
    Map<String, String> attributes = new HashMap<String, String>();
    // ....
}

As we already have a pre existing production database, so ideally the values of attributes could map to the following existing table:

create table example_attributes {
    example_id bigint,
    name varchar(100),
    value varchar(100));
