[Xdoclet-user] Composite key problem

Laurent Duperval Wed, 03 Nov 2004 13:49:25 -0800

Hi,

I'm trying to generate mappings for a lot of my classes which have composite keys. For all such classes, I created an ID class called <ClassName>Id.java.

When I run my task to generate the hbm.xml files, I get an error. Does anyone know what could be causing this?

My class look like this:

public class Indattyp
{
   private IndattypId primaryKey;

 .
 .
 .

   /**
    * Getter method for composite key.
    * <br>
    *
    * @return composite keyinputDataTypeLid
    * @hibernate.id
    */
   public IndattypId getPrimaryKey()
   {
       return primaryKey;
   }

   /**
    * Setter method for composite key.
    * <br>
    * @param newKey the new value to be assigned to primary key
    */
   private void setPrimaryKey(IndattypId  newKey) {
       this.primaryKey = newKey;
   }

 .
 .
 .
}


public class IndattypId implements Serializable {
   private Integer inputDataTypeSid;

   private Integer inputDataTypeLid;

   /**
    * Getter method for inputDataTypeSid.
    * <br>
    * Meta Data Information (in progress):
    * <ul>
    * <li>full name: indattyp.INPUT_DATA_TYPE_SID
    * <li>column size: 5
    * <li>jdbc type returned by the driver: Types.SMALLINT
    * </ul>
    *
    * @return the value of inputDataTypeSid
    * @hibernate.property column = "INPUT_DATA_TYPE_SID" not-null= "true"
    */
   public Integer getInputDataTypeSid()
   {
       return inputDataTypeSid;
   }

/** * Setter method for inputDataTypeSid. * <br> * Attention, there will be no comparison with current value which * means calling this method will mark the field as 'modified' in all cases. * * @param newVal the new value to be assigned to inputDataTypeSid */ public void setInputDataTypeSid(Integer newVal) { this.inputDataTypeSid = newVal; }

/** * Setter method for inputDataTypeSid. * <br> * Convenient for those who do not want to deal with Objects for primary types. * * @param newVal the new value to be assigned to inputDataTypeSid */ public void setInputDataTypeSid(int newVal) { setInputDataTypeSid(new Integer(newVal)); }

   /**
    * Getter method for inputDataTypeLid.
    * <br>
    * Meta Data Information (in progress):
    * <ul>
    * <li>full name: indattyp.INPUT_DATA_TYPE_LID
    * <li>column size: 10
    * <li>jdbc type returned by the driver: Types.INTEGER
    * </ul>
    *
    * @return the value of inputDataTypeLid
    * @hibernate.property column = "INPUT_DATA_TYPE_LID" not-null= "true"
    */
   public Integer getInputDataTypeLid()
   {
       return inputDataTypeLid;
   }

/** * Setter method for inputDataTypeLid. * <br> * Attention, there will be no comparison with current value which * means calling this method will mark the field as 'modified' in all cases. * * @param newVal the new value to be assigned to inputDataTypeLid */ public void setInputDataTypeLid(Integer newVal) { this.inputDataTypeLid = newVal; }

/** * Setter method for inputDataTypeLid. * <br> * Convenient for those who do not want to deal with Objects for primary types. * * @param newVal the new value to be assigned to inputDataTypeLid */ public void setInputDataTypeLid(int newVal) { setInputDataTypeLid(new Integer(newVal)); }


This is the error:
