AduitInfo class is just a normal java bean. For example,
package xyz;
import java.sql.Time;
import abc.vo.PersonVO;
public class AuditInformation
{
private PersonVO createdBy;
private Time creation;
private PersonVO editedBy;
private Time lastEdited;
public AuditInformation()
{
}
public AuditInformation(PersonVO createdBy,
Time creation,
PersonVO editedBy,
Time lastEdited)
{
this.createdBy = createdBy;
this.creation = creation;
this.editedBy = editedBy;
this.lastEdited = lastEdited;
}
public PersonVO getCreatedBy()
{
return this.createdBy;
}
public void setCreatedBy(PersonVO createdBy)
{
this.createdBy = createdBy;
}
public Time getCreation()
{
return this.creation;
}
public void setCreation(Time creation)
{
this.creation = creation;
}
public PersonVO getEditedBy()
{
return this.editedBy;
}
public void setEditedBy(PersonVO editedBy)
{
this.editedBy = editedBy;
}
public Time getLastEdited()
{
return this.lastEdited;
}
public void setLastEdited(Time lastEdited)
{
this.lastEdited = lastEdited;
}
}

Can you give us a sample of what the AuditInfo class might look like?
