How to name foreign keys?

[taavi]

Hello everybody,

I have a simple newby question. How can I name inside the ejb3 entity, the foreign key name.
I have right now entys like this:

import java.util.Date;

import javax.persistence.Entity;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

import ee.zero.mis.data.ABaseBean;
import ee.zero.mis.data.IMisEntity;
import ee.zero.mis.data.common.Person;
import ee.zero.mis.data.common.Project;
import ee.zero.mis.data.tm.classificators.WorkType;

@Entity
@Table(name = "Report")
public class Report extends ABaseBean implements IMisEntity{

 private static final long serialVersionUID = 644015895309221489L;

 public final static String DATE = "reportDate";
 public final static String PERSON = "person";
 public final static String PROJECT = "project";
 public final static String DESCRIPTION = "description";
 public final static String TIME_COUNT = "timeCount";
 public final static String WORK_TYPE = "workType";

 private Date reportDate;
 @ManyToOne
 private Person person;
 @ManyToOne
 private Project project;
 private String description;
 private Long timeCount;
 @ManyToOne
 private WorkType workType;



 public WorkType getWorkType() {
 return workType;
 }
 public void setWorkType(WorkType workType) {
 this.workType = workType;
 }
 /**
 * @return Returns the description.
 */
 public String getDescription() {
 return description;
 }
 /**
 * @param description The description to set.
 */
 public void setDescription(String description) {
 this.description = description;
 }
 /**
 * @return Returns the person.
 */
 public Person getPerson() {
 return person;
 }
 /**
 * @param person The person to set.
 */
 public void setPerson(Person person) {
 this.person = person;
 }
 /**
 * @return Returns the project.
 */
 public Project getProject() {
 return project;
 }
 /**
 * @param project The project to set.
 */
 public void setProject(Project project) {
 this.project = project;
 }
 /**
 * @return Returns the timeCount.
 */
 public Long getTimeCount() {
 return timeCount;
 }
 /**
 * @param timeCount The timeCount to set.
 */
 public void setTimeCount(Long timeCount) {
 this.timeCount = timeCount;
 }
 @Temporal(TemporalType.DATE)
 public Date getReportDate() {
 return reportDate;
 }
 public void setReportDate(Date date) {
 this.reportDate = date;
 }


}

And the SQL created from that entity is like this

 alter table Report
 add constraint FK91B14154EE046B3A
 foreign key (workType_id)
 references Classificators;

 alter table Report
 add constraint FK91B141545BD8D7EC
 foreign key (project_id)
 references Project;

 alter table Report
 add constraint FK91B141542860EA88
 foreign key (person_id)
 references Person;

My question is, how is possible to change foreign-key name from FK91B141542860EA88 to this fk_test_key

Thanks for alla help
