    As i know, the entityBean cann't join the two tables. entityBean can only map one row of one table.

    I am not aware how you join the tables or map the fields using Entity beans ,but i suppose the problem is in the
    Deployment descriptor of your application.
    Check whether database and field mappings are correct in your deployment descriptor.
