EJB 3.0 PFD6 problems

[aidan_b5]

Hi, I've just upgraded Jboss 4.03SP1 from EJB PFD 5 to 6....jboss starts ok except when it reaches one of my entity beans I get the following exception:

09:49:14,109 WARN [ServiceController] Problem starting service persistence.units:ear=SMSPortal.ear,unitName=objentity

The class apparently causing the problem:

@Entity
@Table (name="persistentproperty")
public class PersistentProperty {

 @Id @GeneratedValue(strategy= GenerationType.AUTO)
 public int getId() {
 return id;
 }

 public void setId(int id) {
 this.id = id;
 }

 @ManyToOne (cascade = {CascadeType.ALL}, fetch = FetchType.EAGER)
 public PersistentKey getPersistentKey() {
 return persistentkey;
 }

 public void setPersistentKey(PersistentKey persistentKey) {
 this.persistentkey = persistentKey;
 }

 public String getValue() {
 return value;
 }

 public void setValue(String value) {
 this.value = value;
 }

 @ManyToOne (cascade = {CascadeType.ALL}, fetch = FetchType.EAGER)
 public PersistentObject getPersistentObject(){
 return persistentobject;
 }

 public void setPersistentObject(PersistentObject persistentobject) {
 this.persistentobject = persistentobject;
 }

 public Date getStartdate() {
 return startdate;
 }

 public void setStartdate(Date startdate) {
 this.startdate = startdate;
 }

 public Date getEnddate() {
 return enddate;
 }

 public void setEnddate(Date enddate) {
 this.enddate = enddate;
 }

 @Transient
 public String getStringstartdate()
 {
 try {
 return DateUtils.getStringFromDate(startdate);
 } catch (Exception e) {
 e.printStackTrace();
 }
 return "";
 }

 @Transient
 public String getStringenddate()
 {
 try {
 return DateUtils.getStringFromDate(enddate);
 } catch (Exception e) {
 e.printStackTrace();
 }
 return "";
 }

 @Transient
 public void setStringstartdate(String startdate) {
 try {
 this.startdate = DateUtils.getDateFromString(startdate);
 } catch (Exception e) {
 e.printStackTrace();
 }
 }

 @Transient
 public void setStringenddate(String enddate) {
 if(!enddate.equals("")) try {
 this.enddate = DateUtils.getDateFromString(enddate);
 } catch (Exception e) {
 e.printStackTrace();
 }
 else this.enddate = Calendar.getInstance().getTime();
 }


 private PersistentObject persistentobject;
 private int id;
 private PersistentKey persistentkey;
 private String value;
 private Date startdate;
 private Date enddate;

 public int getPrevious() {
 return previous;
 }

 public void setPrevious(int previous) {
 this.previous = previous;
 }

 public int getNext() {
 return next;
 }

 public void setNext(int next) {
 this.next = next;
 }

 private int previous;
 private int next;

}

Comparing the sizes of the Hibernate jars reveals a lot has been added....does anyone know what has changed as this code worked perfectly fine in version 5.

Is there some new annotation that I've missed?

Help Appreciated Thanks!
