         class="model.Contato"
         column="codigo"/&gt;
    &lt;/class&gt;
&lt;/hibernate-mapping&gt;

contato.hbm.xml

&lt;?xml version="1.0"?&gt;

&lt;key column="cod_contato"/&gt;
&lt;one-to-many class="model.Cliente"/&gt;
    &lt;/class&gt;
&lt;/hibernate-mapping&gt;

acredito que seja os relacionamentos tem um relacionamento de 1 para n de contato para cliente

O set em Contato deve ficar assim:

<set name="cliente" inverse="true">
    <key column="cod_contato"/>  
    <one-to-many class="model.Cliente"/>
</set>

Como a mensagem diz, a coluna codigo foi mapeada duas vezes, uma como id da tabela e outra como chave para uma associação many-to-one. Dá uma olhada melhor nisso. Será que faz sentido o many-to-one ficar na mesma coluna do id?

obrigado pela ajuda quinelato

&lt;many-to-one  
          name="contato"  
          class="model.Contato"  
            column="codigo"/&gt;

O que eu estou tentando fazer aqui é apontar para o codigo da tabela contato que no caso é FK na tabela clientes, e no cliente ele se chama cod_contato.
Aluma outra forma de fazer isto?

Se você mapear somente o “cod_contato” como many-to-one:

<class name="model.Cliente" table="cliente">
        <id name="codigo"></id>
        <property name="nome"/>
        <property name="cidade"/>
        <property name="uf"/>
        <property name="rua"/>
        <property name="numero"/>
        <many-to-one
         name="cod_contato"
         class="model.Contato"
         column="cod_contato"/>       
    </class>

maldito seja o hibernate nao funciona este 1:n alguem pode ajudar?
o codigo ta ai em cima

Gobain 6 de nov. de 2007

Então, a única coisa q eu vi q parece errado pra mim é o fato de vc não ter tirado a coluna cod_contato do mapeamento Cliente.hbm
Aqui em baixo eu tirei ó!

&lt;?xml version="1.0"?&gt;  
&lt;!DOCTYPE hibernate-mapping PUBLIC  
   "-//Hibernate/Hibernate Mapping DTD 3.0//EN"  
   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"&gt;  
&lt;hibernate-mapping&gt;  
    &lt;class name="model.Cliente" table="cliente"&gt;  
        &lt;id name="codigo"&gt;&lt;/id&gt;
        &lt;property name="nome"/ 
        &gt;&lt;property name="cidade"/&gt;
        &lt;property name="uf"/&gt;
        &lt;property name="rua"/&gt;
        &lt;property name="numero"/&gt;
        &lt;many-to-one  name="contato"  class="model.Contato"  column="codigo"/&gt;         
    &lt;/class&gt;  
&lt;/hibernate-mapping&gt;

Esse tá certinho

&lt;?xml version="1.0"?&gt;
&lt;!DOCTYPE hibernate-mapping PUBLIC
   "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"&gt;
&lt;hibernate-mapping&gt;
    &lt;class name="model.Contato" table="contato"&gt;
        &lt;id name="codigo"&gt;&lt;/id&gt;
        &lt;property name="nome"/&gt;
        &lt;property name="cidade"/&gt;
        &lt;property name="fone"/&gt;            
        &lt;set name="cliente" inverse="true"&gt;  
            &lt;key column="cod_contato"/&gt;    
            &lt;one-to-many class="model.Cliente"/&gt;  
        &lt;/set&gt;  
    &lt;/class&gt;
&lt;/hibernate-mapping&gt;

lgweb penso que quando mapeias um deves ter nessa classe uma propiedade do tipo Set

Se mapeias assim:

<set name="cliente" inverse="true">
    <key column="cod_contato"/>  
    <one-to-many class="model.Cliente"/>
</set>

acho que deves criar a propriedade cliente na classe Contacto assim:

private Set<Cliente> cliente = new HashSet<Cliente>();

e os getters e setters habituais.

Espero ter ajudado.

Gobain 7 de nov. de 2007

É verdade, não havia reparado no código, mas o set tem q ser incluso na classe Contato um Set para os Clientes e na classe Cliente um

private Contato contato;

Ai galera valew mesmo ajudou mto , to iniciando com o hibernate nao sabia desse esquema de set agora to começando a entender sempre que vc usar um set vai ter que ter um list na classe para representa-lo é isso?

l1nk 7 de nov. de 2007

Se mapeias um estás a indicar que tens um Set definido na tua classe.

Um Set é uma interface que te permite declarar por exemplo um HashSet() e nao uma List.

Se queres usar uma List deves mapear no hibernate usando a tag .

Tem atenção que este mapeamento é diferente do .

Bom trabalho.
