Hibernation cache annotation area attribute not working

I have a spring / springwebflow app (app A) that uses the Hibernate second level cache as well as the request cache. The application reads only from the database, not add / update / delete statements.

Requests are cached in one region called "daoCache". I installed this by annotation on namedQuerys

I have an annotated object from Hibernate @Cache with an attribute scope set to "daoCache" too

@Entity
@Table(name = "GROUP_OPERATOR")
@SequenceGenerator(name = "SEQ_GROUP_OPERATOR", sequenceName = "SEQ_GROUP_OPERATOR")
@NamedQueries( {
@NamedQuery(name = "findGroupOperatorByMaster", query = "FROM GroupOperator groupOperator WHERE groupOperator.segment IS NULL and groupOperator.pointsMaster.pointMaster like ?",
    hints={@QueryHint(name="org.hibernate.cacheRegion", value="daoCache"),
       @QueryHint(name="org.hibernate.cacheable", value="true")})
})
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY, region = "daoCache")
public class GroupOperator implements Serializable{
 ....

In addition, I have another application (app B) that connects to the same database and performs add / update / delete on the same database

20 , A. , , B, A 20 .

, , A "select * from group_operator, point_master = 1000". , , groupOperator # 1. ( 20 ), , №1. .
