getFieldDescriptorByIndex()

[Ricardo Giacomin]

Hi,

I'm giving OJB my first try and found a problem which I believe to be
probably my mistake.

I have a 1:n association between Job_specification and Job_type.

When I retrieve a spec, the aJob_type field has a null value. I debugged and
saw that method ObjectReferenceDescriptor.getForeignKeyFieldDescriptors()
works fine. The problem seems to be in the method
ClassDescriptor.getFieldDescriptorByIndex(int index). Its implementation
returns the descriptor at position (index - 1), instead of index. When I
change this implementation to return m_FieldDescriptions[index], everything
works fine.

Since this is probably a very common and recurrent scenario, I think the
problem is with my configuration (see repository.xml below). Or is this
really a bug?

Any help would be appreciated.

Thanks,
Ricardo.

PS.: I could not find anything related to this in the ojb mailing lists
archives.

My repository.xml states the following:

<class-descriptor
  class="uol.job.store.Job_specification"
  table="JOB_SCHEDULER.JOB_SPECIFICATION">

  <field-descriptor id="0"
    name="iDT_JOB_SPECIFICATION"
    column="IDT_JOB_SPECIFICATION"
    jdbc-type="BIGINT"
    primarykey="true"
  />
  <field-descriptor id="1"
    name="iDT_JOB_TYPE"
    column="IDT_JOB_TYPE"
    jdbc-type="BIGINT"
  />

  ...

  <reference-descriptor
    name="aJob_type"
    class-ref="uol.job.store.Job_type">
      <foreignkey field-id-ref="1"/>
  </reference-descriptor>

</class-descriptor>

<class-descriptor
  class="uol.job.store.Job_type"
  table="JOB_SCHEDULER.JOB_TYPE">
  <field-descriptor id="0"
    name="iDT_JOB_TYPE"
    column="IDT_JOB_TYPE"
    jdbc-type="BIGINT"
    primarykey="true"
  />
  <field-descriptor id="1"
    name="dES_JOB_TYPE"
    column="DES_JOB_TYPE"
    jdbc-type="VARCHAR"
  />
</class-descriptor>


My Job_specification class is defined as:


public class Job_specification
{
  private Long iDT_JOB_SPECIFICATION;

  private Long iDT_JOB_TYPE;

  private Job_type aJob_type;

  ...


  public Long getIDT_JOB_SPECIFICATION()
  {
     return this.iDT_JOB_SPECIFICATION;
  }
  public void setIDT_JOB_SPECIFICATION(Long param)
  {
    this.iDT_JOB_SPECIFICATION = param;
  }


  public Long getIDT_JOB_TYPE()
  {
     return this.iDT_JOB_TYPE;
  }
  public void setIDT_JOB_TYPE(Long param)
  {
    this.iDT_JOB_TYPE = param;
  }

  public Job_type getAJob_type()
  {
     return this.aJob_type;
  }
  public void setAJob_type(Job_type param)
  {
    this.aJob_type = param;
  }

  ...
}
