Same old question (composite-d)

Hibernate version: JBoss4.0.1, Hibernate2.1

I know this has been gone through endlessly and I have been through all the post following the search on all forums.

I have got my composite-id working (and tested etc).

My problem is I cannot get the XDoclet to produce the correct hbm file for this composite-id (I have been to CodeHaus and seen XDoclet2 etc etc too).

At the moment I have repaired the hbm generated by XDoclet and overwrite the autogenerated one with my hand coded one (in my Ant scripts).

I cannot see a workaround to this (it seems the solutions are in the pipeline but not quite there yet).

To complete the story:

My composite table is Person_Organisation_List (person_id and org_id being primary keys with an extra (non-primary) attribute called designation, and no I cannot alter the schema).

Code:

public class PersonOrganisationList
{
   private String         designation   = null;
   private PersonOrgListPK   primaryKey   = null;

   /**
    * 
    * @hibernate.property column="designation" type="string" length="40"
    *                     not-null="false"
    */
   public String getDesignation()

...
   /**
    * 
    * @hibernate.id 
    * 
    */
   public PersonOrgListPK getPrimaryKey()
...

Code:

public class PersonOrgListPK implements Serializable
{
   public Long   person_id   = new Long(0);
   public Long   org_id      = new Long(0);

   public PersonOrgListPK()
   {
   }

   public PersonOrgListPK(Long person_id, Long org_id)
   {
      this.person_id = person_id;
      this.org_id = org_id;
   }

   public Long getOrg_id()
...

   public Long getPerson_id()
...

The hand repaired PersonOrganisationList.hbm.xml looks like:

Code:

        <composite-id
            name="primaryKey"
            class="PersonOrgListPK"
        >
      <key-property name="org_id" type="long"/>
      <key-property name="person_id" type="long"/>
        </composite-id>

No matter what I do, at the moment XDoclet (v1.2.2) only produces

Code:

        <composite-id
            name="primaryKey"
            class="PersonOrgListPK"
        />

Your almost there:

You need to add the @hibernate.property tag(s) to the Key properties itself.

Much obliged squire, that did do the trick.

And for posterity's sake,

All I had to do was to add the property tags to my PrimaryKey class

Code:

public class PersonOrgListPK implements Serializable
{
   public Long   person_id   = new Long(0);
   public Long   org_id      = new Long(0);

   public PersonOrgListPK()
   {
   }

   public PersonOrgListPK(Long person_id, Long org_id)
   {
      this.person_id = person_id;
      this.org_id = org_id;
   }

   /**
    * @hibernate.property name="org_id" type="long"  
    */
   public Long getOrg_id()
...

   /**
    * @hibernate.property name="person_id" type="long"  
    */
   public Long getPerson_id()
...
