I have this class which is a composite of other classes. One of the composite, Role is
itself a composite of class, Recipient. But the XMLEncoder stops at Role designating it as
PersistentBag. Apparently, XMLEncoder doesn't go any further because it is not a
bean.
Has anybody developed a persistentDelegate to deal with PersistentDelegate and
"unravel" XML all the way to the edge of the object graph?
Thanks in Advance.
Here is the "central" class:
|
| public class ServiceNotification implements Serializable
| {
| private long id;
| private List<Role> roles;
| private Application application;
| private Event event;
| private String name;
|
| public ServiceNotification(){}
| public ServiceNotification(Application app, Event event, String name)
| {
| this.application = app;
| this.event = event;
| this.name = name;
| }
|
| @Id
| @GeneratedValue
| public long getId()
| {
| return id;
| }
| public void setId(long id)
| {
| this.id = id;
| }
|
| @OneToOne(fetch = FetchType.EAGER, cascade={CascadeType.PERSIST, CascadeType.MERGE,
CascadeType.REFRESH})
| public Application getApplication()
| {
| return application;
| }
| public void setApplication(Application application)
| {
| this.application = application;
| }
|
| @OneToOne(fetch = FetchType.EAGER, cascade={CascadeType.PERSIST, CascadeType.MERGE,
CascadeType.REFRESH})
| public Event getEvent()
| {
| return event;
| }
| public void setEvent(Event event)
| {
| this.event = event;
| }
|
| @OneToMany(fetch = FetchType.EAGER, cascade={CascadeType.PERSIST, CascadeType.MERGE,
CascadeType.REFRESH})
| public List<Role> getRoles()
| {
| return roles;
| }
| public void setRoles(List<Role> roles)
| {
| this.roles = roles;
| }
|
|
|
Role contains recipients
|
| public class Role implements Serializable
| {
| private long id;
| private String name;
| private List<Recipient> recipients = new ArrayList<Recipient>();
|
| public Role(){}
| public Role(long id){this.id = id;}
| public Role(String name){this.name = name;}
|
| @Id
| @GeneratedValue
| public long getId()
| {
| return id;
| }
|
| public void setId(long id)
| {
| this.id = id;
| }
|
| /**
| * @return Returns the role_name.
| */
| public String getName()
| {
| return name;
| }
|
| /**
| * @return Returns the recipients.
| */
| @ManyToMany(fetch = FetchType.EAGER, cascade={CascadeType.PERSIST, CascadeType.MERGE,
CascadeType.REFRESH})
| @JoinTable
| (
| name="ROLE_RECIPIENT",
| joinColumns=@JoinColumn(name="ROLE_ID",
referencedColumnName="ID"),
| inverseJoinColumns=@JoinColumn(name="RECIPIENT_ID",
referencedColumnName="ID")
| )
| public List<Recipient> getRecipients()
| {
| return recipients;
| }
|
| /**
| * @param recipients The recipients to set.
| */
| public void setRecipients(List<Recipient> recipients)
| {
| this.recipients = recipients;
| }
|
|
| /**
| * @param role_name The role_name to set.
| */
| public void setRole_name(String name)
| {
| this.name = name;
| }
|
| public void setName(String name)
| {
| this.name = name;
| }
|
|
|
The XML output is:
