Foreig key must have same number of columns as the referenced primary key

Hello!

I developing a web application with NetBeans. I'm trying to integrate hibernate into my project in order to set/get information from Database.

After create the Hibernate Reverse Engigeering file and Mapping Files, using NetBEans wizard, I found one proplem executing HQL:
org.hibernate.MappingException: Foreign key (FK637007E11D64F93:muxes [location_id])) must have same number of columns as the referenced primary key (locations [name,network_name,network_type_id,country_id])

at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1286)
at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:859)

My table locations has 4 columns for primary key, but my table muxes has reference to location id in order to be unique, i don't know how to solve this problem.

And the maping files are:
Muxes.hbm.xml

<hibernate-mapping>
    <class name="etna.test.Muxes" table="muxes" catalog="etna">
        <composite-id name="id" class="etna.test.MuxesId">
