xdoclet and hibernate

[Nick15]

Hello
I'm searching some examples about how can I generate a composite id with the tags of the XDoclet.
Can you help me?

Hi nick

Code:

/**
* @hibernate.class table="table"
*/

public class ClasswithCompositeId  {

    private ClasswithCompositeIdPk PK;


    /**
     * @hibernate.id generator-class="assigned"
     * 
     */

    public ClasswithCompositeIdPk getPK() {
        return this.PK;
    }

    public void setPK(ClasswithCompositeIdPk thePK) {
        this.PK = thePK;

        return;
    }

}

package saes.election.eligibleoption;

import java.io.Serializable;

import org.apache.commons.lang.builder.*;

public class ClasswithCompositeIdPk implements Serializable {

    /**
     * The composed eligible option this role is related to
     */
    private Class1 key1;

    /**
     * The candidate this role is related to
     */
    private Class2 key2;

    /**
     * @inheritDoc
     */
    @Override
    public boolean equals(Object o) {
    
    }

    /**
     * @inheritDoc
     */
    @Override
    public int hashCode() {
  
    }

    /**
     * @hibernate.many-to-one column="key1_code" outer-join="true"
     */

    public Class1 getKey1() {
        return this.key1;
    }

    public void setCandidate(Class1 key1) {
        this.key1 = key1 ;
    }

    /**
     * @hibernate.many-to-one column="key2_code" outer-join="true"
     */

    public Clase2 getClave2() {
        return this.key2;
    }

    public void setCandidate(Class2 key2 ) {
        this.key2 = key2 ;
    }

}

        <!--
            To add non XDoclet property mappings, create a file named
                hibernate-properties-RoleData.xml
            containing the additional properties and place it in your merge 
dir.
