Hibernate version: 2.1.6

Code between sessionFactory.openSession() and session.close():
VendedorClientePOPK vendedorClientePK = new VendedorClientePOPK();
VendedorClientePO vendedorCliente = new VendedorClientePO();

vendedorClientePK.setCodCliente( '11111111000299' );
vendedorClientePK.setCodVendedor('222');

session.load(vendedorCliente,vendedorClientePK);

Full stack trace of any exception that occurs:
net.sf.hibernate.ObjectNotFoundException: No row with the given identifier exists: com.probel.fatura.data.VendedorClientePOPK@855379[codVendedor=222,codCliente=11111111000299], of class: com.probel.fatura.data.VendedorClientePO

--> but the row exists.

Name and version of the database you are using:
Oracle 9i

The generated SQL (show_sql=true):
select vendedorcl0_.COD_VENDEDOR as COD_VEND1_0_, vendedorcl0_.COD_CLIENTE as COD_CLIE2_0_ from vendas.VENDEDOR_CLIENTE vendedorcl0_ where vendedorcl0_.COD_VENDEDOR=? and vendedorcl0_.COD_CLIENTE=?

I replace "?" by correct values, execute it in the SQL Plus and it works.

//Table columns:
COD_VENDEDOR char(6)
COD_CLIENTE char(14)

//PK Class
public class VendedorClientePOPK implements Serializable {
private String codVendedor;
private String codCliente;

...

public boolean equals(Object other) {
if ( !(other instanceof VendedorClientePOPK) ) return false;
VendedorClientePOPK castOther = (VendedorClientePOPK) other;
return new EqualsBuilder()
.append(this.getCodVendedor(), castOther.getCodVendedor())
.append(this.getCodCliente(), castOther.getCodCliente())
.isEquals();
}

public int hashCode() {
return new HashCodeBuilder()
.append(getCodVendedor())
.append(getCodCliente())
.toHashCode();
}
}

//Persistence Class
public class VendedorClientePO implements Serializable {
private VendedorClientePOPK comp_id;

...

public boolean equals(Object other) {
if ( !(other instanceof VendedorClientePO) ) return false;
VendedorClientePO castOther = (VendedorClientePO) other;
return new EqualsBuilder()
.append(this.getComp_id(), castOther.getComp_id())
.isEquals();
}

public int hashCode() {
return new HashCodeBuilder()
.append(getComp_id())
.toHashCode();
}
}

If anybody can me help, I'm grateful.....
