I use Hibernate -core 3.6.9 , mysql connector 5.1.10 and hibernate spatial 4.0-M1 Thanks for any advice.

EDIT: This exception causes query.list(); from this(point type is POINT):

public List<?> findByCompany(long companyId) {

    Session session = sessionFactory.openSession();
    Query query = session.createQuery("select  point from GeoPoint");

    List<?> rows = query.list(); 
        return rows;

Answer 1

The query looks strange for an hql query, try:

Select p from GeoPoint p

Answer 2

From the Hibernate spatial web site I see the following:

Hibernate Spatial version 4.0 is compatible with Hibernate 4.x

But you say you are using Hibernate core 3.6.9. Maybe you need to upgrade your Hibernate version?
